1. When I’m out with a friend and we meet someone they know but I don’t, and that person makes no effort to introduce themselves to me or include me in the conversation. Like, I know I’m the designated Less Hot Friend but you don’t have to remind me of it.

2. Overstaying your welcome or inviting yourself to things. I had a friend who wouldn’t take no for an answer. Like get the hint. It’s midnight and you’ve been here all day.

6. Inviting everyone in the friend group to an event and excluding just one friend then proceeding to talk about how much fun they’re going to have at said event in front of the person that was purposely excluded, in front of everybody.

7. People who leave their litter and uneaten food all over fast food restaurant tables, and the floor area.

9. When they walk into an elevator before you have a chance to get off. Same with buses and subways.

10. When they turn everything into a one-up contest.

12. Instead of apologizing they retort with, “I’m sorry you feel this way.”

13. When they don’t tuck in their chair after getting up.
