[Boober tugs down the brim of his hat, feeling uncomfortable in his helplessness here. The idea of a friend forgetting who you are entirely sounds too awful to stand... But he can't just lie and pretend to know this guy. ...Right? Right, no, that would be stupid.]

That's awful... Look, if I talked to you a bunch, I'm sure we were friends. I don't talk a lot to people unless I care about them...care about them a-a lot! I'm just not comfortable getting close to most people, so...

I don't know if that helps, or makes it worse, or what. But there you go.
