I was called in to speak to DS' teacher today at 3 about a playground incident, school finishes at 3:30. When I arrive I ask how DS has been in class today and am told that she hasn't been in the classroom due to personal commitments today. She goes on to discuss the incident - basically a game that got out of hand resulting in another boy getting hurt - we're chatting for quite a while when I notice the time and ask if DS is definitely aware that I am in with her, she says yes and carries on talking. I manage to "escape" at just before 4pm and make a dash for DS classroom, other teacher in there says that DS has gone home! I find him in tears having come back to school thinking, his words, he'd never see me again. I am furious about the lack of communication but not sure what to do.
