My dad has an appointment at my hospital, and beforehand I'm going to show him around. But his appointment is MONDAY (Monday, darn it!), and even though he told me this repeatedly I didn't get it. I waited around at our proposed meeting place today until I realized something was up, then (after some discreet inquiries and leaving a phone message at my folks' place) I decided his appointment had been cancelled, when it was never for Friday in the first place!
We're straightened out now, though. Things are cool. Dad called me after I left a message and deadpanned (he's good at deadpan) "Boy, I hate it when my son knows more about my schedule than I do..."
