There was a kid in my first grade class that would always find the gum under tables and start chewing on it. He would also lick the bottom of his shoe when we came in from recess. He was like twice the size of the other kids and I think he had pica because he would pick at the walls and try to eat that as well.
Nice enough guy though.
That's neither here nor there though. The point is, these things have consequences. Let's raise the next generation better than our own and teach them never to stick gum to tables.
