a tip

When you are subbing always try to make friends with, and acknowledge the troublemaker in the nextdoor classroom. When passing in the hall, give them a thumbs up or ask if they are still on "green." At least, look them in the eye and smile. Then, when you find yourself in their classroom, they will remember that you took the time to talk to them and they may not be so hard on you that day. Just sayin...
