pink kittie - I wouldn't worry too much, you will probably end up with the person with whom you are the best match. I don't know how you all choose your bigs/littles, but if you are allowed to choose more than one, put them in order of the person you think you'll be the closest to as friends.
Update, everyone: I set out all her stuff last night & our chapter room looked like awesome, woohoo! Last night was "Zetalicious strawberry stuff", so the room was covered in strawberry EVERYTHING. All of us big sisters are setting out chocolate-covered strawberries this afternoon.
I also gave some bunny slippers that wouldn't fit my little anyhow to another girl for her little. Lots of us shared stuff with one another when a particular person didn't have certain things - especially things like balloons, tape, paint pens, poster board, and ribbon lol.
The littles are allowed in the room from 5-8:30pm only, so after that we'll start decorating for tomorrow. I can't wait to set out the stuff for tomorrow - BUNNIES!!! It will truly look like Easter in there on Tuesday. I don't think my little has any clue (that I'm her big), and I hope she doesn't figure it out till the revealing.
