It became very windy during the night. Both bedroom windows were open, and we were woken by one banging back and forth. The Sage got up, so I went back to sleep. The sound woke me again several times during the night, but it wasn't until 5 o'clock that I could be bothered to get up and deal with it. I closed the offending window, checked the other one was on it's keep-thing (must have a proper word, the sticky-up bit that the hole in the bar fits on to) and went back to bed. Of course, I read and played games until it was nearly time to get up, and then went back to sleep.
Later, I suggested to the Sage that it would be a good idea always to make sure that the bedroom window was secure. "I got up," he said. "It was secure, but it was so windy that it was banging anyway."
I pondered this for a moment. "Which window?" I asked. "The one above the side door," he said.
"Um. That wasn't the banging one. You didn't check the window on the other side of the room, then."
It appeared not. There didn't seem any point in asking why, in any case, he hadn't shut the window he thought was banging. One doesn't necessarily think quite straight at 2am.
