Twice. The second time I told him I’m going to register a complaint with the apartment complex, and let the police deal with knocking on his door. He didn’t say much, he was drunk and stoned out of his mind. But I had a toddler, and had to be at work at 4 am, so his 2 am shenanigans seriously impacted me, and my patience was gone after the second offense. Thankfully there was never a 3rd.
