I think my friend has been harrassed and bullied
Have you talked to your friend about it?
I'm asking you. I was reading your other questions.
Is it really serious? If your friend is in danger because of this, you might want to contact the police.
I'm not calling the police, I will tell the bullies to stop and make sure my friend is okay.
I think that's also a great idea. I hope you can get them to stop and help your friend!
