Dd has had a stand in teacher for about a month. New to school. Today dd told us that her teacher did a silly thing. Apparently teacher got angry because some of the class were being noisy. She slammed a glass jar full of marbles on the table, which broke and sent marbles flying. Part of me (a big part) feels sorry that someone would get so frustrated that they would do that. But part of me is cross that a teacher would lose control like that. Wibu to contact school about it?
