I'm really surprised by the people that are just adding guests! We invited all of our singles with guests, so that's not the problem. The problem is that family members are adding their children, or other unidentified guests. For example, we got one back that used the M____ line for their last name, which starts with M, and put that *6* will attend. But it just says Mc family, so we actually don't even know who it is (we were not smart enough to number the cards because FI didn't think anyone "would be that dumb"). This is FI's side of the family, so he called her and said, "Hey, we definitely didn't invite a family of 6, so can you help me figure out who this is so we can get in touch with them?" And she said, "Well, FI, you can't invite some people in the family and not others." Actually, we can. We chose not to invite people that we have never met or haven't seen since we were less than 15 years old. I guess I just thought that our family would be a little more understanding, especially since we are paying for this whole shindig ourselves. I'm all about calling people who over-RSVP and saying, "Sorry, but we can't have any additional guests." Am I wrong?
