Lolly Willowes by Sylvia Townsend Warner — Read

The Willoweses came back to London about the second week in September. For many years the children's schooling had governed the date of their return; and when the children had grown too old for school, the habit had grown too old to be broken. There was also a further reason. The fallen leaves, so Henry and Caroline thought, made the country unhealthy after the second week in September. When Laura was younger she had sometimes tried to argue that, even allowing the unhealthiness of fallen leaves, leaves at that time of year were still green upon the trees. This was considered mere casuistry. When they walked in Kensington Gardens upon the first Sunday morning after their return, Caroline would point along the tarnishing vistas and say: "You see, Lolly, the leaves are beginning to fall. It was quite time to come home."

It was useless to protest that autumn begins earlier in London than it does in the country. That it did so, Laura knew well. That was why she disliked having to come back; autumn boded her no good, and it was hard that by a day's train-journey she should lose almost a month's reprieve. Obediently looking along the tarnishing vistas, she knew that once again she was in for it.
