people who don't respond to text messages promptly
jackets without pockets
super drunk people at the bar who try to make conversation with you, and ask questions like "so, tell me your life story...how did you and your fiance meet? when did you know he was the one??" ugh, please leave me alone i'm trying to get drunk here
people who don't notice non-verbal cues or get the subtle hints you drop when you're trying to leave or you want them to stop something they're doing without being blunt and/or rude to them. c'mon people, pay attention and take the hint already
