When I'm cleaning windows

Household chores took on an unexpected twist today. With friends visiting I was tasked with cleaning the downstairs front room windows, and I took this on with gusto. The end result was not too bad, as I hope you will agree (though I did not earn an honest bob).

As I was packing away I noticed this Red Underwing lurking by the window frame. Somehow I had failed to notice this (lets face it, quite large) insect in the previous 20 or so minutes! I was obviously concentrating hard on getting a nice gleaming finish.
