Gah, that’s a lot of stories to sort through.
As far as long stories go, I’d say “Jock,” “Identity Crises,” and “Letters From Prison” would be my top three is some order or other.
As for short ones and vignettes, that’s a bit harder. Looking through them, there are a lot that I *like* or thought were successful, but no real favorites. I would like to expand a few at some point, but that’ll have to wait for another time.
