I hear you. It was fortuitous because it was the one night when my wife was away with our son on a trip. I finally had the house to myself, and my neighbor (drummer) just happened to be on a walk with his wife that night when he heard me. I was bummed that after living in apartments for 20+ years, the one night I had alone in my own home where I could practice late, someone was coming by to (what I thought) complain. My neighbors had a party last weekend that went on well past 11pm. They might have a party like that once or twice a year. They are considerate people and cutting loose once or twice a year is acceptable. Demanding perfect neighborhood silence 365/year is unreasonable and not very neighborly.
