Check who you were responding to. Also recognize that this is not just a 2 or 3 person conversation: for example, my reply to V50's post was not really meant for him, it was meant for everyone. So to, with his. And, when in doubt, I think it is better to say the obvious than to assume people know it, particularly in a thread like this, where so many have wrong assumptions. And while not saying the obvious assumes people know, saying the obvious is a matter of protection: don't assume the person is suggesting you don't know. [Edit] And to be frank, I find your and many others' thought processes here to be underdeveloped/disorganized. People have a lot of gut feelings and perceptions on these issues, many of which are actually wrong or off point. That's part of the reason I state the obvious: because it apparently isn't.
