I've met people who sit on boards that I'm amazed can dress themselves in the morning, never mind be trusted with a box of matches. I bumped into one such person I'd worked with when he was visiting the next company I worked for. I'd just left my office and heard a banging sound coming from my right. I looked around and saw this imbecile's face pressed against the glass window in a door. He'd somehow managed to trap himself in the fire escape stairwell. I'm still not sure who was more surprised to see the other, me or him.
I probably should have let him out, really...
I reckon people put me in the same category. When I first became a director the first thing anyone said to me was “fcuk me, you couldn’t direct pi55 into a bucket”. True story.
