I agree that kids who engage in problematic behavior should not be painted in a horrific manner. I think even the word bully Carrie’s with it a very negative label.
But, if you share that I peed in your orange juice when you were a kid, everyone laughed at you, and you still have anxiety related to this traumatic event, then it does not follow that you a) do not recognize how my own age and development was a variable in the behavior, and b) have not let it go.
The consequences of the experience can linger long after you have forgiven, or let something go. Further, you could understand perfectly well that the behavior I exhibited then was not communicative of my character now, or even a comprehensive example of my behavior or character then.
When a person speaks about the trauma they have experienced and the consequences, we cannot, without more, assume an entirely separate narrative on a separate discussion based on the shared element of the problematic behavior, for those two discussions .
