What are curtains for?

The most common practical use of curtains of course is for privacy. And Dylan would fully agree. When the curtain was closed, he ventured behind them and became very quite. I thought that something outside caught his attention.

Nope. Several minutes later we discovered that the curtains had become a secret hiding place for doing #2. He probably felt like he was incognito, but little did he know we caught it on camera.
