Sam and Dean in “Unfinished Business”

Sam

I respected him. But no matter what I did, it was never good enough.

Dean

So what are you saying? That dad was disappointed in you?

Sam

Was? Is ...always has been.

Dean

Why would you think that?

Sam

Because I didn't want to bow hunt... or hustle pool, because I wanted to go to school and live my life, which in our whacked-out family made me the freak.

Dean

You were kinda like the blonde chick in The Munsters.

Sam

Dean, you know what most dads are when their kids score a full ride? Proud. Most dads don't toss their kids out of the house.

Dean

I remember that fight. In fact, I seem to recall a few choice phrases comin' out of your mouth.

Sam

You know, truth is, when we finally do find Dad... I don't know if he's even gonna wanna see me.

Dean

Sam, Dad was never disappointed in you. Never. He was scared.

Sam

What are you talking about?

Dean

He was afraid of what could've happened to you if he wasn't around. But even when you two weren't talkin' ...he used to swing by Stanford whenever he could. Keep an eye on you. Make sure you were safe.

Sam

What?

Dean

Yeah.

Sam

Why didn't you tell me any of that?

Dean

Well, it's a two-way street, dude. You could've picked up the phone.
