I’m a terrible person, I know
I think that people can evolve as they mature. Recognizing that you don’t like the person that you used to be and taking steps to be a better person doesn’t make you a terrible person at all.
I also did and said a bunch of things in my teens that I abhor and regret as an adult, but I think that I grew into a respectable person and speak out against the very things I have said as a child.
Learning to have a conversation and not a monologue is also a pretty solid skill.
People stand there talking without a break and I just stop listening.
