We're all living that Asian family joke. Parents spend their whole lives waiting for their kids to thank you. Kids spend their whole lives waiting for their parent to say "I'm sorry." That said I've never felt that way about my Mom and Dad. I've faults and problems a plenty but I wouldn't ascribe any of that on them; indeed the best things about me seem to clearly come from them and the worst are just as clearly thin…
It's cool, but sometimes you wanna cry for that child. As an adult, I've heard the mistake is looking at what happened to you through a childs eyes. Ya can't really ever let it go.
