I was listening to the radio as I was driving to work. The topic of conversation was about drink driving. It was one of those items that was foremost in my mind when my sons began driving some years ago. I was terrified that they would have a few pints and get into a car.

To be fair, I’ve watched them through the years organising their driver much more diligently than we ever did at their age. I’ve always been happy to collect them in an emergency and that has given me peace of mind too.
