Well, Purdue won't have that ONE same annoying person you have been writing about. You DO get along with your advisor except for whatever he has been doing with this guy, and maybe this is your way out of the situation. My cousin's cousin was Purdue's Golden Girl a million years ago, that's how the hankster became a baton twirler, true fact! The travel sounds like fun, I would a) maybe make sure the pest isn't following you there? and b) figure a bird in the hand is worth two in the bush. how frequently do people get offers that they can pick and choose between them? how soon do you have to decide? oh yeah - CONGRATULATIONS!!!
