This is a place to share our nice, sweet, and fun experiences with our students.
Some students are sweet only to manipulate and get what they want.
I agree that most kids are genuinely good, and I enjoy interacting with them. Well, I agree with the original poster to a certain extent. Certainly, in some cases you paint a very manipulative view of students. I feel that it would foster an environment where students would have no respect for you and would constantly be trying to get one over on you. You will become ineffectual.
