It was bound to happen...

... and today it did. I wasn't thinking. I wasn't paying that close attention. She was talking, we were joking, and it just slipped out. The "S" word. In class. To a student. I said "shit." I am mortified. I apologized, I told the principal, I called the mom, I apologized profusely. They all laughed and said "it's ok." I'm still mortified. Ugh.
