"That's weird." Mac pulls a face at Sam. What kind of robot doesn't feel good laughing at other people's misfortunes? That's what misfortune is for, either cautionary tales or comedy. It seems like a waste of good suffering to just like another person's unhappiness go ripe on the vine. "Maybe I wouldn't get it, I'm an only child, which means I got all the attention.*"

Then Sam goes on to be cryptic, and, well. "What, like the mafia?"

*Mac sincerely believes this, despite the fact that "all the attention" mostly covers forging his parent's signatures for report cards and being left to drive himself to the hospital when his appendix burst the summer between 9th and 10th grade.
