My friends who are international students feel the need to document many, many moments, so I have to smile on command a lot. I just do a regular smile, showing my teeth, BUT I have this weird gap between my lower and upper rows of teeth, so a tiny bit of my tongue always peeks through. Sometimes people look at this in photos and ask me why I was sticking my tongue out. It’s kinda embarrassing, but not too bad. I try to remember not to do that when I’m taking some kind of “important” shot.
