This inescapable loneliness has been cast down upon me my whole life.

We had lunch dates where you gave me fatherly advice.
You'd email or call to check up on me. 

You can't tell a girl without a dad that she's like the kid you never
had but always wanted...

Then buy her some things, carry them up to her apartment, and make a move on her.
...I'm not yet that perverted.
