To recap, my upstairs neighbour is a night-owl with a pitbull and a tumultuous lovelife.
Also, his deck is my roof.
We have had several run-ins and things threaten to get ugly, especially with the warmer weather coming. The most recent was 4 weeks ago where he, his girlfriend, and his dog had a heart-to-heart on the deck at 5:30 am. I had to go out on the deck and tell them to put the dog inside.
e.g. Last night he and his girlfriend are on the deck (circa midnight) in a profanity-laced shouting match. To his credit, for once, the damn dog wasn't out on the deck. However, I nearly got involved, in part because I need sleep and in part because it was pretty intense and I was getting worried about violence.
So I'm sitting up in bed for 10 minutes with the lights on, debating if I should throw on my clothes and go out on my deck. Or to call the cops.
Ultimately, I did not, and things settled down.
