An Honest Mistake

He said to the judge 'twas an honest mistake
He walked out in front of me and i forgot to brake
He did not even scream though there was a loud thud
And he lay prostrate by the road on the mud
Just a broken left leg sir he did get off light
But he has threatened to sue me he says that is his right
The police charged me with dangerous driving the reason I'm before you today
For an honest mistake sir what's my price for to pay?
But the judge said an honest mistake whilst driving in your defence of little use
For injuring somebody that's not an excuse
With suing you for damages the injured person should go ahead
Though he is rather lucky he is not with the dead
And an honest mistake in your case is a crime
And for that you can serve seven months of jail time.
