“There is nothing like a doorbell to precipitate the potential into the kinetic. When you stand outside a door and push the button, something has to happen. Someone must respond; whatever is inside must be revealed. Questions will be answered, uncertainties or mysteries dispelled. A situation will be started on its way through unknown complications to an unpredictable conclusion. The answer to your summons may be a rush of tearful welcome, a suspicious eye at the crack of the door, a shot through the hardwood, anything. Any pushing of any doorbell button is as rich in dramatic possibility as that scene in Chekhov when, just as the Zemstvo doctor's only child dies of diphtheria and the doctor's wife drops to her knees beside the bed and the doctor, smelling of carbolic, takes an uncertain step backward, the bell sounds sharply in the hall.”

“Has someone or something pushed your anxiety button? Answer it with prayer!”

“Ronkers was getting out of the elevator on the first floor when the intercom paged 'Dr Heart'. There was no Dr Heart at University Hospital. 'Dr Heart' meant someone's heart had stopped.'Dr Heart?' the intercom asked sweetly. 'Please come to 304 . . .'Any doctor in the hospital was supposed to hurry to that room. There was an unwritten rule that you looked around and made a slow move to the nearest elevator, hoping another doctor would beat you to the patient. Ronkers hesitated, letting the elevator door close. He pushed the button again, but the elevator was already moving up.'Dr Heart, room 304,' the intercom said calmly. It was better than urgently crying, 'A doctor! Any doctor to room 304! Oh my God, hurry!' That might disturb the other patients and the visitors.”

“Good God, man, what is that smell?" He eyed with disgust the doctor's filthy cloak."Life," answered the doctor.”

“How are you, Rory?' [the Doctor] asked.I [Rory]... answered him. 'It's been odd being you.''Isn't it?' The Doctor's smile didn't quite reach his eyes.'How do you cope?''Ah...' The Doctor picked away at a scrap of loose paint on the door. 'Well, I just get as close as I can to a happy ending, then I shut the door behind me and move on.'I nodded.We shut the door behind us and moved on.”

“When we get to the door I reach for the doorbell but Carlos steps in front of me, grins and then starts banging on the front door with all of his might. The door shakes and his pounding thunders throughout the house. (...) We must be the world's loudest burglars.I shout, "Why are you pounding so hard?"His grin gets even larger. "If anyone's home, they'll definitely answer that knock. If nobody's home what difference does it make?”
