But you're a scientist!?!

I have been taking ice skating lessons at the rink next to my office after work on Monday nights. Presidents day I did not work, but I still had ice skating. I offered to ER to brush his teeth before I went to my fitness class. He wanted to know what it was. I told him I was learning how to become a beautiful ice skater. To which he replie, "But Mommy, you are a scientist."  I have some education to do that the two are not mutually exclusive!
