Liar. About the age part, not the birthday thing.
I didn't even know I was turning 36 tomorrow, and I am your twin.

You better not blow spit all over my face when you are blowing the candles out this year. That was so gross.
for your excellent birthday,
I thought long about,
what I could sendja,
that would knock you out.

I thought I could sendja
a sweet pink t-shirt
but then I thought
you already have one, so that would be unnecessary.

eventually I knew
just what to sendja
for your birthday, katie,
I got you...

(open the card)
I'm late, but that's okay, 'cause aparently you're still only 35. Happy birthday. =)
