Green in the face
◊ When you are at a movie with someone who you broke up with less than a week ago, do not say "Ooooh, I love this song!" and start dancing in your seat when an Al Green song plays in the background until you have precisely identified which Al Green song it is.
Because, of course, if you are dumb enough to groove along, the song will be "Let's Stay Together" and you will freeze with your fists in the air while your brand-new ex stares at you like he can't figure out if you're crazy, incredibly vicious or a moron, and possibly all of the above.
Bit of a faux pas, that.
