Because I have no idea. I've been throwing around a bunch of ideas, from just doing something at home, to having it at Applebee's (or something of that nature), to a "nicer" restaurant. Where did you go/what did you do?
As for parents, mine don't care what we do and offered to help pay no matter what we do. His parents have been mum about it...which is actually fine because they make me crazy whenever they bring up anything about the wedding.
