Am I a Magpie?

Why do I want these sparkling earrings so very much even though I'd be too cowardly to actually wear them around? Perhaps I am a human magpie.

"In common with jackdaws, magpies are attracted to shiny objects and are notorious for stealing rings and other jewelry left on windowsills or tables out of doors."

So, keep a close eye on your jewelry when I'm around! Just kidding.
