Okay so I also posted my birthday party question (See post titled irritated) on the local board and granted I did ask if I was being a biotch but here's one of the responses I got.
"Sorry, I think you're being a b!tch. Sure, I'd be annoyed, but it's your birthday, not your wedding. Babysitters are super expensive. "
Too funny... I guess I just don't understand because I don't have to pay to leave my dog at home. : ) One more reason dogs are great!
