how old are you? I ask because it means less as you get older. if you're under 30 I say claim mom brain, beg forgiveness and call her now. if you're over 30 call her tomorrow and claim mom brain and it also doesn't hurt to throw in "my kid was (insert disgusting bodily function here) and it completely slipped my mind so sorry!"
Re: Fah-reak. Today is my BFF's b-day and I just realized it.
Oops!
You're not a bad friend...just a forgetful one ; )
That SUCKS.
You could still call her or just call her tomorrow and give her extra love.
Ugh. Well, today is also my ex's bday. Is it bad that I *didn't* forget?!
