Schoolboys are capable of bullying ~ this is news?

My experience, as a former child and as a father of three, is that boys at their worst can be very mean, and certainly more physically violent than girls, but girl bullies can be hateful on a deeper psychologial level, and won't let up as readily or quickly as their male counterparts.

It's almost a cliche, and a common occurance in fiction and movies, etc. ~ two young men come to blows and then, as soon as one or the other gets a bloody nose or whatever and cries "uncle," the two are suddenly the best of friends, arms over each others shoulders, knocking down a few drinks together, etc.

This is a cliche because it has some basis in reality.

The same kind of thing is much less likely to occur in a conflict between females (of any age).
