LOL! I got a tellin' for supposedly not reading the post correctly, when it turns out it wasn't
written correctly?!

That's good!

Anyway, the cheek air-kiss is pretty universal, isn't it? Nothing odd or 'metropolitan' about it. I don't really do it myself, but squillions of others do. I shake hands if I am meeting you for the first time, and if you're a friend, I usually give you a quick hug, without the cheek kiss.
