Computer Genius

As I was trying to open a Microsoft Word document, the mouse arrow froze in the center of the screen. I waited a minute, tried moving the mouse again - still frozen. With a sigh, I restarted the computer. Still the mouse seemed frozen. Just before hitting the restart button again, I glanced down at the mouse and noticed that the red light wasn't on. A different kind of light went on - one in my sluggish brain - as I realized that the batteries in the mouse simply needed to be replaced.

I'm a computer genius.
