I was a teacher for over a five year period, I learned a lot about other people's life from my experience. Most teachers rushed to beat a child for as simple thing as not having a Biro or book and I asked them, have you ever considered buying the books for the kids and then wait for them to throw it away?
If a child comes to school without brushing, what do you do? Beat the child or get him a toothpaste?
My dear. I taught a few months too and it really was an experience.
