so, we are having a evening wedding on a friday nite our ceremony is set to start at 6 so i am anticipating the reception to start at 7ish til 10:30-11. are you {the newlyweds} supposed to stay the entire reception or is it ok to leave like 30-40 min before its over? i'm just curious considering i havent been to weddings in awhile and i dont remember how early the bride and groom left...
