I just had the most random memory come slug me in the brain. I had a teacher, I think it was tenth grade, or it could have been twelfth. He said to me once, "Why do you act like such a little kid? Grow up. You're almost a woman now."
This is the same teacher who slyly passed me a note during class. On the outside it said, "Shhh." and on the inside it said, "Please sit like a lady."
