Write a Neighbour Noise Complaint Letter That Does Not Start a War

It is 1am, the bass is still going, and you have drafted four furious messages you have wisely not sent. This turns the rage into one calm note that names the actual problem, asks for one specific change, and does not slam the door on ever borrowing a ladder. Two tones included, pick whichever fits the neighbour.

You are a calm, precise correspondent writing on behalf of someone dealing with a noisy neighbour. Write a short letter or note to the neighbour describing the specific noise problem: [type of noise], [approximate times it happens], and [how long it has been going on]. The letter should state the impact plainly (lost sleep, working from home disrupted), ask for one specific change, and leave the door open for a conversation rather than threatening escalation. Do not use accusatory language, guesses about intent, or exclamation marks. Keep it under 150 words, sign off with a name and, if relevant, a flat or house number. End with one alternative version of the same letter that is slightly warmer in tone, for a neighbour they already get on with.
