This is not creepy-crawly, I promise.
There's an old cabinet in our barn that was there when we bought this farm. It was once a decent piece of furniture, with its wide shelves and sliding glass doors. Probably sat in someone's dining room. But somewhere along the way it absorbed a spill that give it a vague odor of insecticide when the doors are left closed. That must have been it for the dining room. We let it stay in the barn, but only use it to store metal things like chicken water cans and water heaters. With the doors open. It stands near the wall, with some old stall doors we stuck behind it 14 years ago.
This morning, for some reason, I looked behind the cabinet while the morning sun was shining in the open barn doors at just the right angle to hit behind the cabinet. And for a moment fourteen years of spider webs were touched by brilliance, turning dusty old webs to spun silver.
