Several times at the weekend and on week- nights our next door neighbour has people turning up to have their cars washed/valeted. His driveway is directly next to ours. The water from the pressure hose gets on our side and on our garage. The car vac often starts at half 9 on Sundays when we're trying to have a bit longer in bed. He's obviously running a business from home. Am I being unreasonable to be pissed off at the noise?
