Two shadows, two birdhouses

The other day I was with my friend Anastasia. She was a bit under the weather so we drank hot tea, nibbled on fine Belgian chocolates and made shadow puppets in the sunlight coming through her window.

While walking through the West Village I spotted a birdhouse in a tree. I found it odd that it had an enclosed porch. Even more curious, was that it had another little birdhouse attached to it. Maybe that little birdhouse should have had one attached to it as well. Then another and another, until microscopic.
