Some assumptions being made about this. kircubbin hasn't said her neighbour is vile, bullying, a fool etc, just that he's been complaining about the leaves. She hasn't said that he bullied the other lady, just that she had offered to pay - perhaps she mistakenly feels the tree belongs to her. I agree that the tree should not be destroyed, it must be a beautiful sight, but sweeping up leaves every year for several years isn't trivial, especially if this man is elderly. My friend, in her late eighties, used to spend all autumn and winter, for about 10 years, raking/bagging up or worrying about all the leaves in her garden. She didn't garden so had no use for a compost heap, she was just worried the garden was messy and the leaves were slippy when she was hanging washing out. She had no trees at all in her garden - the trees were her neighbours' lovely mature specimens, and not once did she ask them to cut them down or complain to them, but the wind direction meant that they didn't get the bulk of the leaves, she did. Family used to help when they could but some days she would be exhausted by it all. And not once did a neighbour offer to help. In the end she moved to a bungalow without a garden. Maybe if you all found a way together ease this man's problems by raking the leaves together, or better still hire a gardener, you could solve the problem without the tree being cut or the old lady spending her savings.
