I was a kid Karen
Why do you feel that you were a kid karen at one point in your life?
I just always wanted to see what I could get away with. This is very similar to the adult Karens out there.
When you're a kid you do some wreckless things, you have admitted it. Karens are terrible screaming people, getting away with things is mentally unstable and and seems like you felt like you were entitled to do what you pleased. Stay away from that sort of mind set now, it will only made you look bad in everyone's eyes.
I don't think I can do that, it is too much responsibility.
Just try your best to have better behavior. It is great that you realize how you act. Now the next step is to better yourself and improve these aspects of your personality.
