In reply to andymac:
Met someone once who, while agreeing that Fred D was a legend, admitted that conversation could be alarmingly one-sided. No matter what the topic started as, it would frighteningly soon become chimneys... or steam engines... or more steam engines... or chimneys.
At least he knew what he wanted - and went for it. Obviously many such folk aren't the easiest to live with. So was it always.
