You move away

You quickly move away from the open door, getting caught spying on the tenants wouldn't be a good way to start off your new job. You walk down the hallway the sounds of their lovemaking fading as you approach the end of the hallway.

Checking the tenant list you see that only three apartments are rented on this floor. Apartment 2B rented to Ms. Robbins was the one with the amorous couple that you just walked away from. Also living on this floor were Mr. and Mrs. Krauss in 2C and Mr. Cohen in apartment 2D. You wonder briefly which one you should introduce yourself too now. As you stand at the end of the hallway between the two doors you can still hear the sounds coming from the open door of Ms. Robbins' apartment. They certainly seem to be enjoying themselves you think to yourself with a smile as you raise your hand to knock.
