This morning I was at my desk working on a blog post when I noticed music playing nearby. It was a little too loud, and it seemed to be coming from another room. I got up, walked to the doorway and hollered for Barbara, “That music you’re playing—where is it coming from?”

“I’m not playing music,” she answered from the back of the house.

So I looked around nearby rooms, found nothing, then returned to my desk only to discover the music coming from my computer. Uh-oh, I thought.
