I had a neighbor once who kept calling me at three in the morning to tell me to make my dog quit barking. The thing was, my dog was sound asleep on the living room sofa! I waited until her swing shift changed and I knew she was leaving the house to go to work at 5 in the morning, then waited until the middle of the week when it would do the most damage, and called her at three to tell her my dog was asleep on the sofa and had been every single time she'd called.
She didn't call again.
