That moment when someone is running in your direction and you think they're running to you so you wave at them and they give you a look.
That moment when there are people in front of your locker and you don't want to be rude to them, but you end up coming off as rude anyway.
That moment when you're talking to your crush and you realize that your bra strap has fallen down your arm and you casually (but not so casually) smoothly (but frantically) struggle to put it up your sleeve and HE NOTICES!!!!
