When I was a very small boy I used to dream of driving a bus, and the bigger the better.
But it didn't take me very long to realize that the job wasn't as glamorous as I had imagined.
And that I probably would never have the skill or the patience to be a good driver.
Which was just as well because it turned out the job could also be dangerous.
So I really can't understand why the Cons behaved so badly in the House of Commons the other day.
