About 3 months ago our neighbours son (18) bought a new car, it’s a small car but he then went and got it modified to have a bloody massive exhaust pipe out on it. He seems to work nights, or be nocturnal as every night for the past 3 months he arrives home between 12.30am and 3am revving the nuts off the bloody car and I have been woken up every single night since he got it. We live in the middle of a big development so we can’t be the only ones being disturbed. It’s gradually pissing me off more and more. Would I be being grumpy to have a word with the neighbours?
