I need your prayers!

This is rediculous.I am willing to bet ,like you say,that you did nothing out of the ordinary.This is the way you are with your students.His Mother is overreacting.Geez ya can't even look at kids the wrong way now a days.When I came home after getting the strap I would get s#*t from my folks,they would never dream of calling the school.
Try to be involved and have a little fun with them and this is what you get.I hope you get to tell your whole side of the story.Good luck.
