If the neighbour's kid can come home at 4am with a loud exhaust, 'thump thump thump' carrying on, and revving it for 5 minutes while it 'cools the turbo down' without a care in the world for anyone else, then I'll bloody well mow the lawn at 5pm on a Sunday evening!
Just so happens my shed is in the corner of the yard adjacent to the garage that he sleeps in. I now have a series of short holes in the slab where I tested a new masonry bit in the hammer drill at 8am on the dot the morning after that. Revenge was very sweet indeed!
There are far worse noise problems - all the cars with illegal loud exhausts, noisy sound systems that rattle an entire block - and they will park for half the night with it running, kids on trail bikes in the local park, neighbours idiot kids banging on the colourbond fence for hours on end trying to make the dog bark, and the favourite pointed out above, the garbage truck at 4.45am on tuesday morning....
Why the hell do they have to rev the crap out of those trucks to drive the 18m to the next bin?
I'd say some sill pollie has had a run in with a neighbour, the cops have told him to go jump with his noise complaint, and now he's waging war.
