My ten-year-old son has recently been misbehaving at school with a friend. First, the teacher informed us that after the class was told not to play hide and seek inside the school building during lunch, he and his friend did so. The most recent offense was that he and a friend were throwing other children's lunchboxes from the trolley, one of which hit a child.
It's disappointing that he did this after promising not to misbehave at school. We've also been teaching him about the power of choices and how choices have consequences, but it appears that he hasn't grasped this concept well enough.
Could you give us some pointers on how to handle this, so that such don't happen again?
