Absolutely,
You spend most of you time trying to understand why you are being yelled at, beaten, kicked, called names, you wonder if it's your fault that your parents fight all the time, you wonder if it's your fault that you were molested by both family and strangers, you wonder if it's your fault that you are bullied mercilessly and beaten daily.
I learned to be afraid of everyone bigger than me, I learned to shut out the world by hiding in my room and listening to music, I learned to always apologize and beg forgiveness for every little mistake real or perceived.
It is all learned, and someday I hope it will all be un-learned.
