A yapping dog and my mixed-up wires created a happy accident
I was at this old house with wooden windows that creaked if you breathed on them. The homeowner's little dog barked at my ladder the whole time I was putting in window contacts. Got my wires crossed, literally, and thought I messed up. But it made the alarm notice real breaks quicker, which the client really liked. A noisy job turned into a better setup for them.
