Whilst performing dull and boring tasks I often find I'm compelled to fidget. I can't help it, and I've always been this way.
A few years ago, I had the pleasure of working for a small ISP in an overly cramped office in London. Space was so tight that my colleagues PC, whose desk was situated across from me, had his PC case rested directly against my monitor. Having his PSU fan blowing in my face was actually quite welcome during the summer time. I would often find my fingers running over the back of his machine during less than captivating conversations, on occasion accidentally removing his keyboard or mouse in the process. Before the advent of auto-sensing voltage PSU's - most power supplies in the UK were sold with a 240/120V switch. Without being consciously involved in the decision process, I somehow managed to push the switch down to 120V. I was immediately awoken out of my slumber by the flash of light, puff of smoke and enormous cracking sound that were emitted at the end of my forefinger. As a result of this traumatic experience, I have now taken up doodling.
