Everyone obliges everyone else, not so much to do something they don’t want to do, but rather to do something they’re not sure they want to do, because hardly anyone ever knows what they don’t want, still less what they do want, there’s no way of knowing that. If no one ever obliged anyone to do anything, the world would grind to a halt, we’d all just float around in a state of global vacillation and carry on like that indefinitely.
