So true

Last week the sensor light on the barn stopped working. Not the end of the world, but something that did need repair. At first I tried adjusting the settings, but that didn't solve the problem of the light not coming on. I then proceeded to taking the unit apart, cleaning the pieces and then reassembled. Well that too proved to not be the answer. Later that night I explained to Sandi the details of the light failure and the rescue operations resulting in failure. It was at that moment that true intelligence prevailed; "Did you change the light bulb"?
