My father was a great man for first impressions. “You only ever get one chance to make a first impression,” he often told me. 

It was only as the years passed I realised that at the heart of that first impression is integrity — a trait that is slowly finding its way into the museum of lost values. I would often watch him shaking hands with someone for the first time as he looked them straight in the eye. I know now that it was integrity he was looking for.
