Student: We can't get this to work right
TA: You can do better *walks away*
I don't even understand, but somehow, my physics TA doesn't use the eraser when he uses the chalkboard. No, when he makes a mistake, he turns the chalk on its side and then swipes it over the writing and then it's gone. He uses the CHALK to erase CHALK WRITING on the CHALKBOARD. That's not possible! Physics TA doesn't care. Physics TA bends the rules of physics, no big deal.
He should pass that knowledge over to my chemistry TA. He ends every recitation coverd in chalk...
