I remember being bullied as a child.
The fact bullying is shameful, and rightly points to deficiencies in the character of the bully, is cold comfort when you're seven years old and some kid with bruises all over his body, no shoes and the reading age of a pre-schooler insists on calling you, inexplicably, The Watermelon.
I also remember being fairly callous to other kids at times, and it makes me shudder to think I may have stopped some of my classmates from enjoying themselves at school.
And, in this digital age, cyber-bullying has introduced a new element to the stress of being young.
Bullying used to be visible and teachers could, and often would, stamp on it. Now it's one phone or computer to another, a beep on your child's phone or an email alert that they have a new facebook message.
