In your group of friends, family, etc. are you the one who arranges social get-togethers or would you rather someone else do it? I try to do it sometimes so that it doesn't all fall on one person, but it drives me up the wall. People don't respond to invitations and then show up anyway, or there's not a date everyone can make it, or someone doesn't want to go with the flow...I'm just done with it. The thing that upsets me the most is the non-response. I'd settle for a "maybe" or an "I'll think about it," but just ignoring emails or invitations is outright rude.
