Ginevive,

How well do you know your friend.? Sounds to me like he is extremiily scared.
what he needs is a quiet place so he can simer.

how bout suggesting to your frrend that you could take him home for a week and keep him in a quiet place until he clams down a bit. I would say give it a week or so and he will be a bit calmer, he may always be a bit more skittish than most bp's as every snake as you know is different
Wouldnt you wanna bite some 1 if they wre knocking on your door all day??

just a suggestion

Chris
