Ah, when you put it that way, it seems like a very worthwhile endeavor!
Don't look at me, I don't understand it either. My sister used to do the home perm thing when we were teenagers. I couldn't stand to be indoors while she was doing that...my dad and I headed out to the garage where the air was much fresher. And worse than the cost of getting nails done is the TIME! I was tortured by one friend who thought all the bridesmaids in her wedding should have manicures and pedicures done the day before it.

I was soooooooo bored! You can't even read a book because you can't touch anything, and all the other women in the place just want to talk about things like manicures and pedicures and what color nailpolish to wear and who does their hair and...

It was painful. And then I ruined the manicure as soon as we got back to her house anyway. Her darling husband had attempted to wash the dishes and put regular dish detergent in the dishwasher, so we arrived home to a VERY flooded kitchen full of suds! It looked like something out of a cartoon. So I grabbed the mop and bucket and started swabbing the deck.
Oh, then the next morning she tortured us by dragging us all off to some hairdressers.

Having someone wash my hair and massage my head was nice, but that only lasted about 5 min...then they do awful things to you like bake your head in some oven-like device, and then tug and pull your hair, and get dangerously close to your forehead with what must be branding irons, and then they rub sticky goop in your hair (why bother having it washed if you're just going to make it sticky), and then gas you with these toxic chemicals sprayed all around your head.

She better stay married, because I'm not going through that again for her. Before that, the last time I went to a hairdresser, I think I was 13 or 14 and thought I wanted a new haircut until I got it and hated it and refused to ever go to a hairdresser ever again. They're evil, sadistic people.
