When I was in elementary school I had a neighbor that was a few years older than me. I thought that it was cool to have a friend who was grades above me, so I'd let her boss me around to keep our "friendship."
I didn't believe her threat until she started walking away. Afraid to lose her friendship, I called her back and handed her the scissors. She sat me down and cut my hair. To my horror she put the locks in an envelope and handed it to my mom before leaving.
