I sometimes sing softly and I'm not even aware I'm doing it. Recently I was wandering around an Office Depot, looking at various desks and chairs. A man smiled sweetly at me, and I realized I can been singing an old love song.

It was a nice moment.

In the days when I played a radio during housework, I could be singing along with it and not even be conscious that I was singing for quite a while.

However, it's been a long time since there was anything on radio that I could stand to have on in the house.
