When I opened the back door this morning I saw a beautiful sight. Three complete spider's webs strung between the hedge and the bay tree. Each was perfectly round and caught the sun like a CD suspended in space, glittering. I then thought how this simile would have been meaningless just a few years ago yet now anyone would know at once what I meant. So the correct image would be conjured up in their heads without the help of my photograph, which failed miserably.
