A sign from above

Today as I stood at a bus stop outside one of the Christmas markets, a pair of glasses fell at my feet. I put them on and found that the bus map I had hitherto been squinting pointlessly at swam clearly into view. My brother was with me at the time, and the only explanation that either of us could come up with was that a passing cyclist had somehow dropped them. We both decided it was a sign of something deep and meaningful, not least that I can't read without glasses, and I kept them.
