Student: Did you grade the tests over the weekend?
Student: Isn't it your job to grade them?
What I should've said: Sometimes I need a break over the weekend. Also, I was a soup kitchen yesterday and I came back exhausted. On Saturday night I was working on computer science for my independent study, and when I got back last night I worked on planning lessons.
What I said: What did you do this weekend?
Student: Hung out with friends?
Me: You have friends?
Other Student: Ha! He went there!
I've got a lot of patience to gain.
