person A: 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_comma_ I was very_comma_ very upset!
person B: That is terrible.  I don't know why teenage boys can be so mean.  What did you end up doing?
person A: I actually knew his father_comma_ so I called and spoke to him about it. I let him know that if it happened again_comma_ I couldn't promise her big brother wouldn't take it in his own hands to defend her_comma_ as he wasn't okay with anyone bullying her.
person B: 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_comma_ though.
