A brief timeline:

12 p.m.: Scheduled time of arrival of A/C repairman (though I was warned he may come earlier)
12:15 p.m.: Time I finished working out. Decided not to shower, since I wanted to be around to let the A/C repairman in.
1:15 p.m.: Received call saying that A/C repairman was "on his way."
2:45 p.m.: Wanting to take a shower, I call A/C repairman to ask where he is. He says he is "on his way" and will be here in 15 minutes.
3:00 p.m.: No sign of A/C repairman. Still haven't showered. Starting to smell. Canceled plans to go to a movie at 4:15 because I still have to grocery shop and cook something for a Thanksgiving potluck at 6:30. Worried that the A/C repairman might not be here even then.

And the saga continues...
