I completely understand- I went through a similar situation with my co-workers and some friends of the family, but I wasn't smart enough to put my foot down so now my invite list is growing and I feel really bad because there are a lot of people invited that I really don't want to come! I'm really crossing my fingers and hoping that they won't come! I'll still have a blast, but I was hoping for something small and intimate...Stick to your guns and don't invite them!!! Good luck!
