And it seems to me that the ones that have an opinion are the people who I couldn't care less if they showed up!
My mom called my Aunt to get my cousin's addresses and she let her know that we weren't inviting children. I don't think that is unheard of, my sister did the same thing 5 years ago at her wedding. However, this was before my cousin's had children. My Aunt was horrified and asked if they could come if "they would be well behaved." That's not why I'm not inviting them, if I included all children the guest list would increase by 30, Aunt also said that I "don't have to feed everybody". Um.... So, if there is a star next to your name you can eat, but if not - so sorry!?!? Also, she complained that we're having the wedding on a Saturday night because one of my cousin's is a bartender. What am I expected to do, have my wedding on a Wednesday night? He doesn't have to come if he doesn't want to lose the money.
Another Aunt scolded my dad because I'm a grown up and he has no obligation to pay for my wedding. My parents generously offered to pay for our venue, catering and DJ. It was their decision, we accepted gratefully and that's that. I completely understand (as do they) that they don't have an obligation, but they want to help!
I guess it's true what they say, opinions are like a**holes, everybody has one.
