Dear Dad,
I'm sorry for leaving you the way I did, I really am. I was very afraid of you, because you used to hurt me. But having experienced more of what life is like, as someone who is "different", I know that everything you did was with good intention. It wasn't your fault. It makes me sick with myself to think that my desertion may have contributed to your depression and early death. I'm so sorry. Please forgive me.
I wish we'd taken the time to get to know each other before you died, but I hope you're proud to know that I've grown up to be just like you. But it means I'm so different from everyone else. Perhaps it would have been good for the both of us, to know that we each had someone else who knew what it's like. For some reason though, we never really talked about anything other than my studies. Ironically, perhaps this is why. Nowadays people are calling it a "syndrome". But I think it's a beautiful thing, to rid ourselves of the complexity and corruption, and embrace our simple-mindedness. It's a part of who I am. It's a part of who we are. People say to me, "You're just like your father", and they mean it as a pejorative. But I glow with pride every time I hear it.
I wonder if you remember the day I passed that exam. For someone like you to react the way you did, I know you must have been the happiest man in the world, at that moment. In the next life, I will recount to you everything I've accomplished since then, and I hope you'll feel that way once more.
