After 2 nights of peace, things got crazy again at 2:30 am.
To their credit, the neighbours stayed off the deck. But it was still loud enough to wake me.
They were clearly on the verge of a total breakup, fighting about money etc.
I stood, blearly-eyed, in my kitchen for 20 minutes trying to decide what to do. Then the woman yelled "let go of me" and it was Game On.
Thankfully I had the phone # for the police station right at hand.
In the mean time, there was no violence. She locked him out at one point, so he was in the open-air hallway, yelling, further buttressing my decision. Things quieted down by the time the cops arrived.
From what I can tell, she may have been leaving, with him nattering at her, just as they arrived. Hard to say. They definitely did not like being greeted by a pitbull at the door. They might have asked him about a license? Not sure.
I slept until 9:45. It is now 10:45. It will be interesting to see if there is any confrontation as I go outside about my business. Hey, I gave him fair warning.
Update: My neighbour left a note. He said he is moving soon, and apologized for being "nothing but trouble" throughout this ordeal.
