"If I'm tense or nervous, I just walk out here. It takes you deep within," says Kathleen, whose own passions center on spiritual healing and personal transformation.
So the garden is a joy at any hour.
Going forward, Thinnes says he'll be "very, very selective" about the plants he buys. These days he's leaning toward unusual ones and natives, for their adaptability and wildlife-friendly qualities.
Good that the major jobs are done, says Kathleen, who thinks "any more would junk up the garden." Besides, Thinnes seems to relish the idea of slowing down and taking his time to get the chores done.
At this rate, he says, "I don't see why we can't stay in this house for 10 or 15 more years."
That's a long time to go without a construction project out back. And how to resist that big pile of graph paper crying out for a pencil?
Hard to know how Thinnes will fare, just as it's hard to tell if he's truly "only kidding" when he mentions something to Kathleen.
"I was thinking of putting a picket fence out front and taking out the lawn," he says casually, as her eyes widen. "We can plant flowers everywhere."
Must be a joke. Sure. Just like "I'm a basic gardener."
