When I was 16, my parents went on holiday and left me at home alone for a few days. We lived in a detached house next door to a pub. It was a hot summer, so I left all the windows in the house open, and played music at full volume, as I partied with a few friends. We even moved the speakers into the garden at one point, to soundtrack our game of football. It was all very irresponsible, as teenagers left alone for the first time often are.
My parents came back, and a few weeks later they told me that several neighbours in the street had been bothered by loud music that they assumed was coming from the pub. Complaints were made against the pub, the council got involved, and the pub's licence was at stake. The pub apologised and promised to turn its music down in future. I knew nothing about this. I just said "that's interesting" and kept my head down. I never told them it was actually my fault.
I still feel a bit guilty about it.
