One tip for dealing with bullying is to be ASSERTIVE. Being assertive is like being half passive, and half aggressive, so you are focusing on your needs and the bully's needs. Being assertive is standing up for yourself, without being offensive.
Okay, I will give you some of my lunch today, only some, because I need to eat, but so do you. Next time maybe ask your mom for more food.
Okay, thank you, I will ask next time.
You see, this boy is being assertive, by focusing on both of their needs.
