Most weekends, some of my friends come by my parent's house where I'm recuperating, for a visit. It's kind of a big thing for me because it's basically the only time I talk to them now; but I don't mention it to my parents other than the "I'm having friends over at X time" that's polite in someone else's house.
My mother keeps asking me, "Are they coming?", with a frequency approaching once an hour as the expected time nears. Telling her "yes" doesn't reduce the frequency but changes the question to "Are they still coming?"
Rrgh. To quote Fraggle Rock, "I fear I may lose my implacable calm."
