Who thinks this boy will grow up to be a rapist/pervert?

There’s this boy at school in my class in first year. He is taller and older than all the other kids in my class and he acts like a pervert with us.

He touches our butts and tries to touch our chests (this is for both girls and boys, he doesn’t seem to care.) He sneaks up behind us and says he likes it when we scream. He got an erection during science class the other day because my friends and I were hugging.

He repeatedly touches my male friend on the butt and always trys to drag him into empty rooms. He calls him “gay” and “homo” afterwards and says that my friend liked having his butt touched really.

In classes, he annoys anyone who is unfortunate enough to be sitting near him by stroking their legs, and if they get up to got to the bathroom he rubs their chair where they sat.

His habits don’t just stand at mildly sexual, they can be violent too and he beat up one boy for calling him a retard. He is mentally ill, I know this, but he shouldn’t be allowed to do stuff like that, right?

The teachers know, his parents know but he continues! I’m worried because if this behavour carries on throughout his life, into his adulthood, he could be a danger to those around him!

Please, let me know what you think!
