<human>: Can you give me the gist of the text in a nutshell?

**The Story:** My daughter (let's call her Marie) and her friend (Sarah) became friends at school (grade 5) when they found out they shared an interest in horses. Marie is a tomboy and likes to play boy games but also likes to play with some of the girls. She says though that she doesn't like the popular girls and the drama that they partake in (makes me a little proud).

Enter Brianna. Brianna is the bully in this story. Brianna tells Marie that Sarah does not want to be friends with her. Brianna basically tells Sarah when she can and can't talk to Marie. Marie was supposed to go for a sleep over to Sarah's this weekend but Brianna put a stop to it. Brianna is one of the popular girls.

When Marie told me all of this I felt like I didn't have a good answer and I didn't know what to do.

Do I call the school and involve them, after all this is bullying. Or do I let the kids work it out?

I know now how other parents must feel when dealing with bullying and I don't want this to get to a point where my daughter feels that she is at fault.
<bot>: My daughter and her friend are being bullied. Do I call the principal and involve the school or do I let them work it out?
