It's bath-time for my friends' son, and after many a bath-watery coffee, he offers me a rainbow drink in a rainbow cup.
"A rainbow drink?" I ask. "How do they get the rainbows down?"
He says, "The rainbow clouds rain rainbow rain down 'til there are rainbow puddles. It makes rainbow trees grow, and rainbow grass. There are rainbow squirrels too. And rainbow houses."
"How do the houses become rainbow coloured?" I ask. "Does it rain on the houses and leave rainbows on them?"
"So everything's rainbow?!" I say with a sweeping gesture.
