My neighbour has a teenager who has autism and is non verbal. I’ve never met the neighbour. The son spends parts of the day on a trampoline in the garden and vocally stims. The noise is loud and due to the positioning of our houses echos so I can hear it in the front or back of my house.
Usually this stops by late afternoon however for the last few nights it’s continued late into the evening, disturbing sleep. Would it be unreasonable to post a note asking for the trampolining to stop earlier?
