Have ever seen someone else get bullied? How did it make you feel?
Newsround has made a special programme all about what it's like to be around bullying, but do nothing about it.
In the show we see 11-year-old Jack do nothing while his friend Liam is bullied at school.
So have you ever been in a similar situation? Have you let a friend get picked on without saying anything? Or maybe you feel you have been bullied and your friends haven't helped you.
Unfortunately this topic is now closed, but there are Comments pages on other subjects on the main Chat index.
We have had a worrying email from Fatima, 13. Please get in touch with ChildLine on 0800 1111 or email them on email@example.com

Amina, 14, London, England
"I don't get properly bullied, but there are people in my year who are just really annoying and they're constantly nicking my stuff, and flicking the catch on my bag so it ends up dangling round my ankles and tripping me up. It's not big stuff, but it happens constantly and it really gets to me and adds up to make me feel horrible. I think it's cause I'm a bit of a geek, and also because I have quite an English accent and everyone at school is English, so they think it's posh. I'm also really skinny, so I get called anorexic even though I'm not."
