We're having a heat wave here in Seattle, but it's a little early for the guy across from me on the bus to be sweating as much as he is. He's strung out and doing calculus problems: a rather surprising combination.
He keeps looking around furtively and wiping the sweat off his face with the neck of his t-shirt. Occasionaly he jiggles his right leg, which is supporting his notebook. He continues writing his calculus, but i can't believe it's legible at this point.
At least he isn't bothering anyone.
