What are stories of rainbows and pots of gold really about? Are they stories of good luck and hope, or of foolish wishes for magical solutions that don’t exist? There are tales both of people tricking fairies and fairies tricking people. So, is it a trait of the person that makes the difference? That is, if you’re clever enough, you’ll snatch the prize from its keeper, but if you’re the simple, gullible type the supposed treasure will turn out to be fake.
Of course, rainbows aren’t magical, pretty as they may be. They don’t actually lead all the way to the ground, so if there were a pot of gold at the end, it would be floating in the sky somewhere, not reachable by people. In fact, I don’t think rainbows generally have concrete “ends.”
But who knows. If you meet a leprechaun, see if he’s feeling generous.
