On the other hand, I must be the greatest neighbour.
When I was living in Omaha, my apartment complex consisted of six unit sections each section with its separate entrance. The layout was three floors of two apartments. Mine was number 5 on the top floor.
My neighbours in unit 6 asked the landlady if there were any vacancies (some friends were moving in the area. My land lady said no.
"But the apartment next to us is empty (number 5)."
"No it isn't, [platapus] has been living there for over five years"
"Really, we never see or hear him!"
It helped that most of the time I was working shift work, but mostly it was because I am a considerate neighbour. If I ever had to move back to apartments again, I want me as a neighbour.
