I've always wanted to drive a lorry. A big one. It's one of my childhood dreams.

In fact, leaving aside childhood dreams of a distinctly teenage, hyper-testosterone variety involving Cameron Diaz, it's my childhood dream no.1. Maybe it's still no.1, whatever.

I never wanted to do it on a regular basis, probably not even more than once. But it's one of those boxes that's remained unticked. Until now.
