Have you noticed that we keep making the same mistakes, and content ourselves with finding new excuses?
Well, I have a friend* who while we were at the University was weekly misplacing his copy of the room key. Nearly every week we were either searching a restaurant, turning the next room upside down, mowing a lawn with our hands, upturning his shirts and trousers, aimless walking round the reading room or just thinking of where next to search. I remember a day, after managing not to misplace the key for two weeks, his mind couldn't adjust to this unusual event and made him believe he has misplaced a key that was safely tucked in his left pocket. That day, we went to every room and restaurant we had been to, we left no sand unseen along the paths we took. And when he heaved and put his hands in his pockets out of exhaustion, the key was found.
