It sounds like you were true to yourself and were honest through the process. Good luck tomorrow. I wish you nothing but the best!
(Of course you personally know what house went with what nickname...I think that many of us here secretly go "ohhh, I hope those are my sisters that she really liked the best!" when we read through these threads. I mean, of course we like our respective homes and get excited when someone else sees how great they are too!...Or maybe that's just me.
) Anyway, lots of luck and try to get some sleep tonight.
