One day, you're coming home from work earlier than usual, which doesnt happen very often. You suddenly hear a loud moan from somewhere, you ignore it thinking it's the neigbours above. You walk closer to your own door and now hear it more clearly. You listen. It's clearly coming from your neigbour, Mary. The quiet girl next door, who almost never talks or makes a sound is moaning really loud thinking none of her neigbours are home. You stand there still for a few moments before heading to your own door. You open and close it quite loud to make sure she hears it. The moaning stops. A few minutes later a quiet knock sounds at your door. You hesitate for a moment, then open it.
