Ok. there's this guy in class who spends every damned second creaking his chair/desk back and forth. It irritates the poo out of everyone in class, but nobody does a thing about it. It's a 3-hour evening class, twice a week, about the neurophysiological bases of abnormal behavior. Today we learned all about (ok, by no means 'all'!) excitatory & inhibitory post-synaptic potentials (EPSP & IPSP); basic concepts, I take it. I sat 2 seats from the creaky guy and glanced over. He was making all sorts of frantic movements: rubbing his eyes, picking at his ears, running his fingers through his hair, . I don't know much about Tourette's, but it would be my best (only..) guess. He let out a few "oh!" utterances. Maybe he was trying to quell an itch of some sort. Poor guy :/
During break I tried squeaking my chair back and forth. It didn't budge. No noise. Nothing. He could have found himself my chair. After discovering that fact, I wanted to glare at him when class resumed, but I'm sure he's got quite enough to worry about. So he squeaked away.
I only wish that people were more considerate of others, no matter what they must deal with on their own.
