I had some amazing teachers, but, none were ever my friends. Do your job. Teach. Set a healthy example for the kids, be an adult, set boundaries. Disciplined. If he's truly pure, then he just learned a valuable life lesson and he should be honored that the school board made an example out of him and he should take some meaning from that.

Sometimes we need people to cross the line a bit so we can reestablish or define where the line actually is. Because things change over time. Good luck to him, though
