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. However, I do not think that students exhibit this behavior any more so than adults. Yes, one must be careful, but that is a lesson in life, not just teaching. I agree it can be a bit frustrating though. Although I would much rather have nice students than difficult ones, I have noticed it is more difficult to draw that line when you have nice students.
