"We can never make proper goodbyes. It was your last ride in a Checker cab and you had no warning. It was the last time you were going to have Lake Tung Ting shrimp in that kinda shady Chinese restaurant and you had no idea. If you had known, perhaps you would have stepped behind the counter and shaken everyone's hand, pulled out the disposable camera and issued posing instructions. But you had no idea. There are unheralded tipping points, a certain number of times that we will unlock the front door of an apartment. At some point you were closer to the last time than you were to the first time, and you didn't even know it. You didn't know that each time you passed the threshold you were saying goodbye."
― Colson Whitehead, The Colossus of New York
