If it is boring and irritating to you, it might be to the child, also. Don't leave them to it when you get tired.

Teachers are workers. They are not necessarily scholars or even thinkers. The industrial revolution needed idiots in the schools to train their workers for the factories. The more boring school was, the more exciting the factory might be.

Teachers are employees. They have to look at the bottom line just like any other worker.

The children are part of the chore for the working teacher. They aren't paid to make friends. They are paid to produce results. Who determines what makes a good result?
