''When we retrieve a memory, we also rewrite it, so that the
time next we go to remember it, we don#t retrieve the original
memory but the last one we recollected.
So, each time we tell a story, we embellish it, while remaining
genuinely convinced of the honesty of our memories.'' G. Musser,
Scientific American
And that's why the fish grows everytime the story is told. They
don't even know they're embellishing an already embellished
story because they really, truly, doggone it believe it.
