I have learned something:

Never to assume someone else hates a class that you hate. Two years ago, in the really slow elevator in Goodspeed and made the mistake of talking to someone I didn't really know about how terrible a class was (and yes, even at the time I knew I should have phrased it better-- how terrible I thought the class was or how much I hated the class). His response: I really like this class.

This time, when someone in the current class that I don't like asked me whether there was homework due tomorrow, all I said was no. Though admittedly, if he didn't know, this class probably isn't exactly his favorite either.
