Putting house up for sale soon. Ex council. Next door are social tenants. Perfectly polite people but very different to us. From our upper bedroom overlooking our (planted, mown and tidy) garden, the garden next door looks awful. They've odds and ends that should be tipped, fag butts on their patio. Broken bikes. Massive trampoline in the middle of the lawn which collapsed and broke years ago... lawn is wild. It looks run down and when looking out it is dispiriting to see it when next to ours.
Would it be unreasonable to offer to help tidy and sort it out? Or should I wind my neck in?
