I hate being strict but I have to do it. In my first job, I had no idea how bad kids could be and they walked all over me. They could do it because I let them. I wasn't strict at all but I learnt from that and now I'm a lot better. Sure you will always get a joker here and there in the class but generally most of the students are well behaved. If only my middle school students would try harder then I would be happy
