So my neighbour doesn't appear to work and is obsessed with doing up his (many) cars. The problem is that our small garden is right next to his drive and garage. He often has the radio on full blast (I can hear it in my house) and is revving engines etc most of the day. We've had to approach them about various things in the past (a faulty outside light/loud parties) and as a result, they seemingly don't like us.
So what do I do about the radio? Leave it or go around and face them again...
