How much does your dad know you?

I grew up thinking that my dad and I were close and that he knew me well, and while he does to some extent know my character traits and what I'm like, I don't really think he knows anything about my likes/dislikes - I don't think he know things about me that are unrelated to school and work. He seemed to know the names of my friends when I was much younger, but I don't think he knows the names of anyone who has been in my life in the past 10 years.

I'm wondering what this is like for others - how much does your dad know you? Does he know all the various aspects of you, or kind of just one dimension?
