I've had quite a few people that I didn't plan in inviting to my wedding say things like "oh I can't wait til your wedding", etc. A few times I have explained that we are only having a small wedding with close friends and family, and I've gotten the response that they would pay for themselves to go. I think it is very rude to begin with to assume you're invited to anybodys wedding, but then to say you'll pay for yourself? How should i respond to that?
