I just received an RSVP from a friend who I was sure was going to come... She was my supervising teacher, and we went through hell together during student teaching. It's a long story, but essentially, we were the only things keeping each other going--our administration HATED us for whatever reason, and it was a really terrible experience.
She had no accessible vehicle, so I would frequently (aka DAILY) pick her up--which meant my commute was an hour and a half. I'd drive her home sometimes, too, and cover classes whenever she randomly called in--including the first day of student teaching! She didn't ONCE give me gas money.
I guess I'm just really surprised.. I was counting on her being there. But then, I don't know why I'm surprised--this is the third time she's flaked on me.
What about you? Have you been surprised or unhappy that someone RSVP'd "no?"
