First, ask yourself: is there bullying in your school? (I can give you an example of my school: there wasn't)
Then ask youself: how can you know that there is? what have you seen? have you seen people crying, being beaten, being forced to do something they didn't want to?
And finally, look into the reasons - i can tell you that my school was so small that we all knew each other's parents, so noone would bully someone while knowing their paretns so close.
