I was in 4th grade and I got back at my bully by secretly eating his lunch
Why did you eat his lunch.
I wanted him to hurt like he hurt me.
It is wrong to get revenge on people who hurt you. It might help get rid of guilt if you reach out an apologize to him.
Nah, I just won't eat his lunch anymore. That stunt I did once served it's purpose. Now he'll stop bullying me.
You would have done better to just do nothing and forgive him for being such a bully. Revenge or retaliation is not really that moral. You will win out on the whole thing if you just ignore him totally.
