Maybe he was just being all poopy because he wanted to throw off the scent of something BIGGER he's doing tomorrow
. I agree with everyone! Work it to your advantage, celebrate it as long as you can, give a teeny break that he at least didn't forget your brithday, just got the date wrong. Maybe he thought it was Thursday and not Wed. I do that all the time.
But LIVE IT UP GIRL!!! HAPPY BIRTHDAY
(tomorrow) AND HAVE A LATTE ON HIM!!
