Because of everything he did, the person I am today is strong, independent, and intelligent. He couldn't afford to miss work when I was sick so he would bring me where I would sleep under his desk with a sleeping bag and I learned a strong work ethic. While we were never rich, when we had money we spent it freely on things to bring memories, never caring about money or being better than anyone else. We moved a lot and I learned to be open to new experiences and people, although that took years of building up my trust after my early, scarred years. He has friends all over the world and taught me to never judge someone based on their looks but to always give someone the benefit of the doubt.
Besides all the lessons he taught me, I watched my biological mother continue to have children and I can compare my circumstances with theirs. I read, have a nice paying job that I love and a husband and am fairly well adjusted. None of my siblings from my biological mother can really say the same.
While the rest of the world tried to tell my father he couldn't be a single dad, he proved them all wrong. The worst thing he could have done is to have not cared about me.
