A little exercise - could be the start of a creative project or just a way to slay some boredom:
Write down ten things you'd like to discover in a rain puddle (there are many near my home now).
Sure a 100 dollar bill (in a Ziploc bag, conveniently) would be nice.
But what else would you like to find?
(Frogs and silver fish? A pockmarked rock? An antique ring? Your own reflection, smiling?)
