i used to work from noon til 12:30 a.m. in the emergency room and i loved it! i prefer that kind of schedule. i think working nights also affects the level of the connections that you make with your co-workers. there's something about knowing that you're all in it together and it made us closer than the day shift. besides, i liked shopping for groceries after i got off work. no other people there. just me and the stockers and checkers.
