The only time I spent more than a few minutes not happy with how I was using the time was the time I was lying in bed tossing and turning and not sleeping, which I don't feel I can blame the con for. There were too many concerts -- I got to 6 but still missed several I either know I would have enjoyed or was curious to find out. Open filk was nice both nights, though more sparsely attended Saturday than I expected. I had to bow out earlier than I wanted Saturday because I was just too tired, but I know I made at least a couple of people happy, so I count the filking a success even though I felt the pain of being out of practice.
Thanks to everyone who offered support and hugs.
