"I still think of you as my son."

I was once riding in the car with my dad, and we were talking. Nothing in depth or serious. I don't even remember what he said that caused him to apologize (I wish I could).

But he said to me, "I'm sorry, its just I guess sometimes I still think of you as my son."

I started to wonder how long he's seen me like that. If he has ever treated me a certain way because he'd seen me as a boy. 

I wonder if anything in my life might have been different if he had seen me as me.
