Six Degrees

You know how sometimes, you find yourself thinking about something, and you realise you don't know how you got there from what you had been thinking about?

Rest-time. A sound like a chainsaw starts up. Of course. They couldn't do it when the kids were awake. S and I go to have a look at what it is. Yep, chainsaw. Cutting up some of the wood from the tree stump they'd cut down.

I go back over to Mark, who tells me: "If there's one ring, the tree's one year old. If there's two rings, the tree's two years old. If there's three rings..."

Amazing.
