I like to look for rainbows.

Tonight we chased rainbows for half an hour past the boys' bedtimes.  It had been a busy day already, but when a rainbow appeared seemingly just around the corner, I couldn't withstand the pressure from the back seats to find the end, capture the leprechaun, or at least steal his pot of gold.
I managed to plant seeds of suspicion that rainbows move.  But the answer to "why?" seemed to always come back to the leprechaun.  Finding myself clinging fiercely to childhood innocence that slips away soon enough on its own, I bit my lip, smiled inwardly, and hummed the primary song: "I like to look for rainbows..." all the way home.
