I told my friend that it was nice visiting my father because we're alike in some way. When I'm with people I'm not related to, I think they are weird, or else I am weird, and sometimes I feel I should be more like them.
My friend's response: "I told Sean you were a robot."
I didn't quite know where he was going with that, but it seemed consistent with the idea that with non-relatives, I feel like an alien species.
He explained, "When I called you, you said you couldn't talk because you were getting your oil changed. You should be able to talk if your car's oil is being changed, so I guess it was your oil that was being changed."
