April comes to an end

So, today I went to sub at a school and was asked if I was a 6th grader by who as it turns out to be the principal of the school. I know I look young but really 6th grade, really?!?!?! When I walked into the office I even had on my BADGE that said SUBSTITUTE TEACHER! Now, I know that sixth graders these days are REALLY tall does that mean that any one shorter than them must be in elementary school? What do you the reader think?
