It's a lovely sunny bank holiday, so everyone is outside, making noises.
With the usual undisciplined dogs barking, there was an additional bark. Thankfully, just a visitor, and the dog was told to be quiet, and obeyed. Two neigbours could learn something from that, but won't.
Then the noisy motorcycle. A guy across the road is often visited by his brother, with a very loud motorcycle, and as they do, needs to rev it constantly before leaving. Now neighbour has got one too. Or did, for today. Took it out of the garage earlier, let it tick over noisily for a while, then revved it a few times before leaving. Why do so many need to make their bikes noisier, the manufacturer has spent a lot of time, and science, makign it develop the right power with acceptable noise. A loud exhaust will usually lose power as it upsets the gas flow, unless as much R&D has gone into the replacement as the original. Unlikely.
A few minutes ago, motorcycle returned. Felt the need to rev it a few times. Then his young daughter (5yrs old?) had a go, standing beside the bike, twisting the throttle. Blipped a few times, then a scream, off the rev limiter, and a bang. Oops. Bike is now in the gargae, and he's cleaning an oil puddle off the drive. Big OOPS!
