I ask Meyer what a bad interaction looks like. “It’s one of two things,” he says. “Either they’re disinterested—‘I’m just doing my job’ kind of thing. Or they’re angry at the other person or the situation. And if I were to see that, I would know that there’s a deeper problem here, because the number-one job is to take care of each other. I didn’t always know that, but I know it now.”
