Gully
Monkey in a seagull suit.
The sad fact is that bullies often act in that manner to make up for some inadequacy in their own life, or to actually mask a more serious problem. Going directly to the parents of the child(ren) may work...unfortunately they may not give a toss, or the child might actually reflect the behaviour that they see at home and consider that to be normal. I know it isn't any consolation, particularly in the case of Miss Coach, but those who bully often go on to lead insignificant and unfulfilling lives...whereas she is more likely to grow up with an appreciation of others.
