““Some people, when they do someone a favor, are always looking for a chance to call it in. And some aren’t, but they’re still aware of it—still regard it as a debt. But others don’t even do that. They’re like a vine that produces grapes without looking for anything in return . . . after helping others . . . They just go on to something else . . . We should be like that. —Marcus Aurelius, Roman emperor A””
