Beware of getting TOO bored that mundane things take on a life of their own...
We used to invent games, play games, mess about when bored...and that was quite often in a large company.
Someone realised if you press 1+++++ and so on, it of course ran a total on our old calculators with big keys (its not rocket science, but it sowed the seed of a game)
So, see how many you can do in 10 seconds, 30 seconds, a minute...it became a challenge to beat your colleague..a very serious challenge that was played out quite regularly.
One day I returned to my office, its empty, and I'm bored. I sat down, scanned my desk, pulled the calculator toward me and started tapping away in my boredom. 1++++++, faster, picking up speed....huh, something moved in the corner of my eye...I glanced sideways...fkit, a visitor is sitting in a small annexe. Bogger, I'm not sure if he can see (or hear)what I'm doing....so I harrumph, frown at the calculator and stab at the keys like somethings wrong with it, the push it away in disgust, hoping if he has seen me, he will assume its faulty and im struggling with it, given up and pushed it away. That sounds plausible....doesn't it ?
