I'm ashamed to admit that I have a few prejudices, but I would like to change.
You don't need to be ashamed. Are your prejudices because of something that happened in your past?
Yes, when I was in 3rd grade I had some really terrible experiences that still influence me.
It is difficult to change ourselves but it is good to recognize when we are doing something wrong or believe in the wrong things and change for the better. It will make you a better person.
Thanks. I'll try my best.
You seem like your really want to change for the better so I'm sure you'll succeed, and be a better person for it.
