I just came out of a meeting where I was asked to provide input on a system I'd never seen before. Needing to defend my 'no comment' position, I found myself saying, "I don't know what I don't know". People around the table who, moments ago wouldn't accept my protestations, simply nodded sagely at this statement and let the matter drop. I can't believe the self evident phrase was accepted so readily. It made me think of other self evident phrases I've overheard in everyday conversations, such as: "Things get older with age" and "It sure gets dark when the sun goes down". My favourite, (though not completely self-evident) I've overheard is, "That Three Musketeers book sure is popular. Look, here's a French translation". Please share your experiences.
