The thread about flaky guests cancelling reminded me of a story my friend told. She had plans to meet up with a high school friend (HSF) but this friend had cancelled at the last minute the last four times they had planned to meet up. My friend keeps making plans with HSF because she is generally a fun and entertaining person to be with (when they actually do catch up)
When do you give up and stop making plans with someone? Have you had any chronically flaky friends/family and how do/did you deal with it?
