One thing you must learn in education, kids, is that you have to have some logical, common-sense boundaries.
Have the kids call you by your last name or last initial if you have an unpronounceable name. Try to not be alone in a room with a student with the door shut. Do NOT NOT NOT become friends with your students on Facebook or MySpace. But here's a new one I learned this week:
Don't sit down. Because some kid may come over and just randomly sit on your lap. And what do you do? Raise your hands so it doesn't look like you are touching or holding that kid there and STAND UP while saying, "I am not comfortable with you doing that."
