Yes, I was wondering how it was that, if her father had been dead for some time, and the farm tenancy presumably moved to a new tenant, her mother still seems to be living in the immediate vicinity, so that Sally can walk straight out of her mother’s garden onto their old farmland. But it sounds as they had farmed a farm on the Dunstall House estate (she says their farmhouse had been at one point the main estate house until the 18thc hall had been built, and was old and substantial, with a formal entrance and a drive lined with oaks), and her mother moved to a nearby cottage, possibly a tied one, after the farm tenancy ended.
She does also present her father being told the tenancy couldn’t be passed on as a key sadness in her own life, that she’d realised she would have to leave the farm, and stopped writing her own stories about animals (and imagining ‘holding my own book with a picture of a penguin on the spine’). But it’s not clear to me whether it would have been at all usual for a daughter to inherit a farm tenancy in the 70s, plus she had an older sister…?
