I just drove home from work - a full hour on the road, nice and sunny, had my shades on music turned up, traffic was okay. And then I get to the traffic lights in the village before mine, catch a glimpse of myself in the rearview mirror and realise that one of the lenses had fallen out of my shades when I put them on.

Yup, that's right, I just drove for an hour with one lens in my shades.....

I used to consider myself fairly intelligent but hey...
