I agree although I can't really see a reason to why someone would throw a wedding party instead of taking care of his/her child who needs the financial support for that - just like you mentioned in the original thread: she will be able to afford if she didn't throw a party.Well in that case you can't really find out the facts, therefore you can't really judge her at all. So I guess if you want to go to the wedding then go, if not then don't. That would be my way of thinking. You are not condoning anything if you don't know the full story.
Nevertheless, there are two sides of every story. She might have the reason that I don't see not really sure!
