that thing where you go to a convention and stress out working the whole weekend and get on a plane the next day and go right back home instead of being able to unwind and spend any time being On Vacation for a day or two
(I'm not doing this at the moment. I'm just thinking about it for some reason.)
My best con experience ever: the time I spent fri/sat in the dealer's room at BentCon selling fuck-all. Was it because gay dudes didn't wanna buy comics about lesbian robots? Or because the aggressive hucksters with a giant pile of yaoi were driving everyone passing away from my table? Either way, Sunday I blew off the con, hopped on the bus, and spent the day bumming around sunny Santa Monica instead.
