angry: One day my daughter came home and told me a much older boy tripped her as she was going off the bus. He did it on purpose, and this made me very, very upset. She was only 10, he was a teenager.

One day my 10 year old daughter came home crying after she got off the bus. A teenage boy purposely tripped her as she was getting off and she got hurt. Needless to say, I was very, very upset!

That is terrible.  I don't know why teenage boys can be so mean.  What did you end up doing?

I actually knew his father, so I called and spoke to him about it. I let him know that if it happened again, I couldn't promise her big brother wouldn't take it in his own hands to defend her, as he wasn't okay with anyone bullying her.

That's good that she has a big brother that can defend her against the bigger kids.  It is just terrible that a teenage boy would act that way to a 10 year old.  No excuse for that.  I hope you don't have to deal with it again, though.
