Sorry, OP but the water spraying comment cracked me up- your neighbour is an absolute nutcase! As someone on the spectrum, neighbour noise drives me nuts but I know it’s my issue and people are allowed to enjoy their gardens (currently fortunately living in fairly quiet place!).
Like other PPs, I’d have said a friendly chat over coffee would’ve been the way forward before, but I think it’s gone too far for that now and I’d be sending a note similar to this:
Dear Neighbour,
I appreciate that everyday noise may be annoying to some, but we are entitled to quiet enjoyment of our home. Last night we were doing just this at a reasonable hour.
Your ‘solution’ of verbally abusing us, followed by soaking us with water, was- I’m sure you will now agree on reflection- a totally unacceptable method to deal with any issue you felt had arisen.
At the very least- I’m sure you’ll agree- an apology is warranted.
If there is any further disruption/threat to our lives, we will have to take further action for your behaviour.
It is worth noting- before you police the street in future ‘incidents’- that reasonable neighbour noise is accepted between the hours of 7am-11pm.
Signed
