Innocent malice hurts the most.
At that time, I was still young and had not seen many things. I always released my likes and dislikes as I pleased. I never thought about whether it would hurt others, and I only cared about what I wanted.
However, when you realize that your behavior has hurt others, there is no chance to apologize.
Both the bully and the bullied have a pain in their hearts that cannot be erased.
