When someone shows up with a new do, we sing them a little song. Most often the boys are the ones we serenade. Unless a girl tells me she got a haircut or gets a drastic cut, it's not easy to tell. Unfortunately, I don't remember who this idea came from, although I'm guessing it was the creative Dr. Jean. I wish I could show you some faces, but I don't have permission. At least you can see their haircut.
Be the kind of teacher who notices new shoes.
