Professor: (Holding my response to a practice essay question) So what should we do with this?
Me: Excuse me?
Professor: We could blow it up?
Me: Um, yeah we could do that. I am not sure I understand what you mean.
Professor: *sigh* It's OK. Don't feel bad. It is a practice problem and so I have no expectations.
Thanks. I know what I will be doing over the weekend. First final = 2 weeks away.
