"Sad Letters" from the teacher .... I am SOO in the #badmumsclub

Last term Ben came home from school with a 'sad letter' from his teacher.  He wasn't alone, a few of his friends also came out of school brandishing the white paper of dread.  Turns out a group of them had been fighting in the playground, teasing another child and then running away.  I was cross.  This was NOT how I'd brought my son up.    Not only was he, rightly, told off for his behaviour by the teacher he has been sent to the Headteachers office with his friends to explain their actions.
   Let me put this in context if you are new to my blog.  Ben is 5 YEARS old. He is a 'normal' kid, that is I cannot hide behind autism or ADHD or another 'problem' for the way he behaves.  yes he lashes out, he's 5, trying to control his temper is really difficult but that's not an excuse.  At the time of this first letter he had been in his reception class for around 4 months.
  Of course we didn't let it go, he was made to apologise to his teacher the following morning when he went into school and had his PS3/ DS time taken away for a week.
