Today I was teaching in a second grade class that had a student teacher. Being a recent student teacher myself, I tried to generate some excitement about her.

ME: I hear you have a great student teacher.
Students: Yeah
ME: What are some of the things you like about her?
Student: She does cool science experiments with us.
Student: She's nice.
Student: I like her because she is a teenager.
ME: Really? A teenager? She looks older than that to me.
Student: I think she's about 18 or 20.
ME: Well how old do you think I am?
Student: Probably about 30.

Turns out we are the same age...
