Microfiction challenge: Looking for pebbles

I did sort of half-promise Michael (of Morpeth Road) that I’d post another oddity to inspire some more weird and wonderful stories. This one, by Frederick Leighton isn’t as exotic as last week’s giant rodent, but it’s a painting that I find lovely in its strangeness. See what you think. Can you get a story out of this painting entitled Greek girls picking up pebbles?
