As he extended his arm to shake my hand, I extended mine, too, in a sweeping motion. Our palms met with a soft pop, and I squeezed assertively the way I’d seen men do at parties when they gathered in someone’s living room to watch a football game.

Receiving it was a rush, an instant inclusion in a camaraderie that felt very old and practiced.
