I too am solar-powered, Pasta. I start to struggle in late January and February unless I spend a lot of time outdoors, or we go away somewhere hot.
Your catering sounds amazing. The most I've managed recently is to turn a surfeit of eggs (many thanks to a neighbour's chickens) and a large block of chocolate into chocolate mousse. I'd forgotten how easy it is.
And how delicious.
I took B&B for what was, by their standards, a very short walk. There was Something in the wheat (partridge? Hare?) but I was very mean and refused to let them trash the crop. I know the farmer (and his wife). He works his socks off on a holding of borderline viability, and is a very kind and helpful man (and his wife is lovely, and appreciates him). So, 'GetoutofDuncan'swheat NOW!' They got out.
As for elderly relatives, I spoke to a lot of mine before they died. My father's side was well strewn about after the nightmares that WWII inflicted on them. They were surprisingly willing to talk about what they'd gone through. I wished I'd got there 10 or 20 years earlier, when more of them had been alive, but I was still able to speak to some remarkable people.
