My older brother told me a funny story the other day. He recently started a new job and is still getting used to how everything works around his new office. So he went to the bathroom and, as he usually does, he took his sweet time. No use in rushing, right? Then, after about ten minutes the lights turned off. And he didn't hear anyone come in. So he thought maybe there was a power outage. So he finished by the light of his cell phone and went to wash his hands. It was at that point that the lights turned back on. In fact, they turned on the moment he exited the stall. That's when he realized that the lights were on a motion-sensor timer to conserve energy. And someone (who probably weighs 110 pounds) had made the decision that ten minutes was enough time for any human being to finish their duties (pronounced "doodies").
So it happened again the next day and my older brother tried throwing a roll of toilet paper over the stall door toward the light switch. And apparently, his aim is terrible when it's pitch-black and he's sitting on a toilet. So the first time he tried to throw it, it bounced off and hit him in the face. And the second time it just didn't register with the motion-sensor (it's probably been calibrated to ignore flying toilet paper). Then he realized he could open the stall door from a sitting position and wave his hand out about an inch. And that did it. But now every time he goes number two at work, he's gonna have to wave in the dark in order to continue. And knowing his luck, someone will walk in one day just as he's opening the stall door. And that will be super awkward. Especially if he's still the new guy.
