I'm still sore about a lot of things that my parents did. If I had to sit here and describe everything that was done, it'd be the size of a 4 page essay about things they did.
Who hasn't been angry at their parents? I know I have throughout the years. Mostly just ya know being a kid and teenager. Nothing major at all thankfully.
I used to resent my parents a lot. My mother was verbally abusive and my father was physically abusive. Now that I am older and more mature I realize that they had their own issues to deal with and didn't seek the proper treatment. If they did they probably would have been better parents. I don't hold that against them, there were less options for things like that back in the day.
