None of us are angels. We are flawed humans that don’t always behave as we should. So how can we recover when we’ve been jerks?
It is a huge mistake to characterize a kid who is behaving badly and bullying as evil. First, it gives them more power over our imaginations then is warranted. And second, it prevents us from doing what we should be doing to stop them.
We are all responsible for being professional and civil and that if a co-worker starts issuing deltas to you to get you to stop doing something they find objectionable, that you should take that as constructive criticism.
