A fact is static, while the perceptual process by which the fact is consumed is elastic.
This is a joke that I have frequently used at work when asked a Yes or No question, to which I reply It depends. Sadly, there are few people who comprehend the joke and, in fact, likely perceive me as rather dense after processing my response. Of course it is possible that I perceive myself as offering a piece of irony which is, in fact, evidence of my density. However, I prefer to perceive myself as rather erudite.
