But if you look carefully, there's more going on. Girl #2 has a very mild condition of esotropia, where one eye points inwards (this particular girl's right eye).
I think there's a good chance you're misdiagnosing/mis-analyzing what's causing the asymmetry of her eyes. Look at girl #3. The main difference between the eye on the right and the eye on the left is that we can see much more lid on the right. This would be a condition known as ptosis ("drooping eye") rather than estropia. The illusion that eye is "inward looking" is created by the fact there is much darker shadow between that eye and the nose, shadow that obscures the white of her eye on that side of her eye. You see this "cross eyed" illusion quite a lot in very old photographs (1800s) where the lighting came from flash powder and the side of one eye was cast into unnaturally deep shadow while the other side of the same eye was washed out. Contrasted with the other eye, which was more evenly lit, the person looked cross eyed, when they actually weren't.

In this photo, there isn't really a darker shadow on the inside corner of that right side eye so much as there is a more pronounced highlight on the outside (viewer's right). They eye on the viewer's left is more darkly lit, but also more evenly, so we can make out the whites on both sides of the iris. If you look at the eye on the left and get a sense of the size of the iris then carry that size over to the right you should see that an "inward looking" eye would require that the iris on that side be much larger than the iris of the left eye, which is unlikely. So, I conclude it's a case of shadow obscuring the white on the inner side. This is confounded by the ptosis, the unnaturally and asymmetrically, heavy lid.

Regardless, I think you're right about the cleft I saw in the hair. It's actually better explained as the interstice between the hair of the two girls after they are compressed together by reflection, and not as a property of one girl's hair.

Tipping:
Where I live it's not really a custom, maybe sometimes if it's a very posh restaurant.
In a run of the mill coffee shop or eatery it's actually more likely they give you, the customer, some kind of discount coupon you can use if you go the same place again.
As for all the small coins, they can be disposed of at a supermarket auto-checkout

what country is that?

Here, one usually rounds to the nearest 50 cent or euro at an average pub, pizzeria or delivery fast food. If you go to a proper dinner, than it's usually rounded to 5 or 10 euro.
At the shop, people usually leave the smallest cent coins to the cashier.

I once went out to eat with my mom. Service was terrible in all respects,
so we left no tip. The waiter came back and said: " ma'am, service is not included "
My mom replied: " Yes, I can tell".

Either. Kissing is kissing. I think they would be embarrassed. I would. I would tell the other side to just hold hands. And even then holding hands is still embarrassing. :blushing:
How can holding hands with someone who is like your mom embarrass you ? You sound like a 50 years old virgin.:biggrin:

I don't think you want because if it costs $18, I'm still leaving only $20. :-p

It is a reasonable tip(11.11% per $18).
I was only joking, I can work jobs that aren't tip based. My point is it is your money so you definitely have the right to use it on whatever purpose as long as you like. Tipping culture I think isn't only about paying for the services you are offered but also about doing some good deeds for the poor as well.

Yesterday I watched a documentary about British show Child genius
I admire the abilities of those kids and I would never be able to solve those questions in such a short time, if ever.
However, it seems to me that being able to calculate long arithmetics from head, memorizing 2 decks of cards and being great at spelling are not necessarily signs of being a genius. Don't get me wrong, it's fantastic if someone can do that. But I don't get why so much importance is ascribed to abilities like these. How does it prove that these kids are better than others or how does winning this show guarantee achievements and happiness in real life.
What some of those parents do in order to make their child win is ridiculous.

allright. I am neither a child nor a genius. Was reading wikipage about Voyager and found this

Edit: beaten to it by Enigman. Although none of those posts were there when I posted this one.

I was reading on how one learns by listening, not by talking. But then if everyone follows this, no one will talk
and there will be nothing to listen to, to learn from...

You have euro too?! I have one and I like it, it looks cool. I have one coin that says "1 EURO Liberté Égalité Fraternité" and has a tree. No idea what it means, but it rhymes. And it looks awesome. It's like a central disc of color silver and an outer ring of color gold.

I also have one that says "Two Pounds, Elizabeth II Dei Gra Reg Fid Def". Also no idea what it means, but it's cool.

I also have one that says "1 Cent Canada, Elizabeth II D G Regina".

:smile:

Yes, that's French version of euro coin. They all look the same on the front side and each country puts their own symbols on the back side (you can pay with any of them in all Euro countries)
Liberté Égalité Fraternité means "liberty, equality, brotherhood" and it comes from the French revolution https://en.wikipedia.org/wiki/French_Revolution
I like euro money, I think it's very nice and distinct colours of banknotes make it easy for people with visual impairment to distinguish between them. The only downside are small cent coins which are almost universally hated and bear almost no value.

But European countries have different living standards, how can they cope with them if they use the same currency like that ?

There are certain standards a country must meet if they want to adopt euro. They concern state budget and debt. Don't ask me about details, I have no idea what they are. Then there is Central European Bank that regulates inflation https://www.ecb.europa.eu/home/html/index.en.html
There are of course problems, like with Greece which has incredible state debt and other countries had to help them. There was a negative attitude towards the help in Slovakia, because we managed to decrease our national debt and the GDP is rising constantly, but we had to borrow a large amount of money for high interest (compared to our economy) in order to send that money to Greece while our own social and healthcare system needs help. But it was inevitable, otherwise there would be huge problems in the eurozone.

Yes, it kind of sucks, but a common market may be the only way to prevent a WW3 by making people feel they are in it together.

Yes, I agree. Though I think it will be much more difficult to create something like the USA in Europe. There is too much history, too much emotions to cope with.

This puzzle should be much easier for you than for Americans.

I had to be shown the answer... :redface:
And then I was like; "Oh. That's right. You have to sometimes think outside of the box, in more ways than one."

I can think of two ways to do it - one is definitely cheating.
Leave the first box blank and use 15 in the others: +15+15=30
Turn the nine upside down to make a six. Then 6+11+13=30

I thought of leaving one box blank, too 15+15= 30

or putting more numbers in one box
(15-5)+(15-5)+(15-5)= 30

Didn't think of that. You can generalise it - (11-1) and (13-3) also work.

Also, 15+15+1 works if we're using base 11 (because 15 read in base 11 is 16 in base 10, and 30 read in base 11 is 33 in base 10).

I have the feeling any "answer" that works actually violates implied constraints.

Yes, I don't see how you can add three odd numbers to get an even answer without some sort of trick answer.
