I mean that, since his skin was brown, he didn't fit into my "white" mental category, because in New Mexico, people whose skins are brown typically identify as "Indian", "Hispanic", or "Black", not "White" (aka "Anglo"). Classifying people into separate "races" is pretty much racist bullshit anyway, but the fact that the classification varies so much from place to place makes that even more obvious.
I didn't actually know he was Jewish until last week.
