The other day I enrolled my daughter for her first school class. The application interview went well. That is, until I was asked: 'What is your occupation?' I was lost for words. The same happens to me each time I go to a party. Inevitably, somebody will ask: 'What are you doing for a living?' I used to call myself a 'usability engineer'. Not that I like the term particularly. But it sounds respectable. Unfortunately, that got me into trouble with the Association of Professional Engineers. You cannot call yourself an engineer unless you are a member. Well, I am not a member. And I am not planning to become one soon, either.
