Birthday cards ideas?

[sam42ification]

So i'm going to a birthday of two freinds of mine (they are twin sisters). I bought them expensive chocolate and wrapped and now all i have to do is write the card. So being an awquard nerd i don't really know what to put on a birthday card. So escapist can you give me some advice about what i should write? They are teenagers before i am accused of being a podofile i am also ashambly a teenager i don't enjoy it but i live with it and they are my freinds so i do have the right to be there. I was going to give a little information about them to give ideas to you guys but i don't really see how it helps. They aren't normal teenage girl either so any ideas you would have for a mainstream girl should thrown away. If they were normal and mainstream i proberly would be invited. So help me what should i write.

Whatever you write, spell it better than that post. Seriously.

Erm... I admit I'm not that good at it, and it would help if you knew them better.

But yeah, spell it right.

What I always find cute with a card for a happy occasion is just a funny little comment about what's on the front of the card, then "*insert "Happy Birthday/Congratulations/whatever the card is about" here* , -*insert name here*"

My sister sent me a cute card with two women eating cake, and she drew on it saying that the one's talking about how delicious and moist it is, then signed it.
What do they like? Just find a card where you can insert an innoculous pop culture reference that they'd get.

Why don't you write them a little story?

Maybe about them?

Maybe about their birthday adventures? Or how they were born?
Don't forget to mention the robot midwife from Mars and the green unicorn that cast three wishes on them, and they had to fight over the spare third one, and it tore open and out of it popped Tom Jones.

You get the picture.
