Is AUTHOR wrong in the post ? POST : My brother is out of the country more than he is home, and this year he is home for his birthday. His girlfriend has planned a surprise get-together the night of his birthday at a bar that he likes, around 8:00 PM. 

I love my brother, and my wife and I would normally be all about going, but my brother and my daughter share the same birthday. 

My wife had talked to his girlfriend and explained that we were most likely not going because it's our daughter's birthday and she seemed to brush it off by saying "It's at 8PM... couldn't someone watch her so you guys can go out?" (paraphrasing.) My other brother's girlfriend seems to feel the same way, even though they have a child and I'm sure they wouldn't leave them on their birthday. 

So, WIBTA for staying home that evening and spending time with my little sweetheart on her birthday?
