I found an interesting quote in one of my favourite books, "The Joy of Cats" (which by the way is about to be republished):

"There's a tiresome young man in Bay Shore.
When his fiancee cried, 'I adore
The beatiful sea',
He replied, ' I agree,
It's pretty, but what is if for?'"

By Morris Bishop

.... so that's what so many people tell me when I explain what I do for a living xD ...
