I've seen bullies hurt a boy and I don't know what to do

Dear Liz,
There are a couple of bullies in my school who are bullying another boy. I feel very sorry for him. He doesn't tell anyone. They steal his money and make him cry. Once they got his glasses and smashed them and threw them in the toilet. Is there anything I can do to put a stop to this. I don't want to get on the bullies bad side either.

Hello Claire,
It's kind of you to want to help this boy, he must be terribly upset. Could you be his friend to start with, it sounds as though he needs one?

Would you be able to tell his mum what has been happening because she needs to go into school about it? If you could discreetly tell a teacher that would be a good idea but don't get into difficulty with the bullies yourself.

What about going to the school office to borrow some sellotape or a pen and then quietly mentioning it to the school secretary?
