I also blame the fact that some of my high school students (when I was a teacher) looked 35! ESPECIALLY the boys. We had some 6'+ kids that had these huge, bulging muscles and major facial hair... If I had seen them at the mall I would have absolutely thought they were out of college, but they were only 17. So when I first started working there, I actually had a security guard try and search my bag (even presenting as female), and I had to kindly explain that I was a teacher, NOT a student. They were quite embarrassed, lol. Makes me happy, though, considering that I am approaching 30 in a few months, and I am quite happy to look younger.
