Gavin commented at lunch today
Gavin commented at lunch today that he's never seen me play with my hair until this week, saying "you must really be nervous." This was interesting to me since I recently told someone that it was not a nervous habit, but rather just a habit. It's one of the reasons I always consider cutting my hair back to shoulder length -- so that I stop playing with it so much, and picking at my split ends. But maybe I was wrong. In that case, I've been nervous for like three weeks running.

(Tongue firmly in cheek .. because I'm just as guilty!) ... BUT you could tell Gavin that you at least have some to play with. :)
Playing with your hair is a sign of flirting.
Disclaimer: I don't know who Gavin is and it could also be a sign of nervousness. Just providing a different perspective ;)
Hmm, in that case, Jen aka Gavin's wife is not going to be happy with me... ;)
lol. Have a good trip.
