When I was in the advertising business, travelling around the world a lot, I used to get irritated by the fact that everyone on aeroplanes seems to have opinions on the morality and otherwise of the business, mostly very similar. (Are people still so allergic to adverts arriving through their mail boxes?)
So in an endeavour to stem the flow, when asked on flights “What do you do?”, I tried to come up with an answer that would put a dead stop to the conversation.
For a while I was in marine insurance. This did quite well. Then, mid-way between Brisbane and Sydney one day, I was asked the usual question by a bloke and came up with the winning formula. I was in dredging.
A long look of puzzlement followed. But words failed him.
