Lost or Found?

A few days ago I happened to come across an earring crudely sticky taped to a power pole on the corner of a busy CBD intersection. What was it doing there? How did it get there? It amused me somewhat to think that someone, no matter what their intension, had taken the time to put it on display. It wasn't an expensive earring, on the contrary, made from fine (brass?) wire formed (or cast) into a pattern with a silver coloured hook. Where was its partner in crime? Ah so many questions with so few answers, but certainly plenty to muse over.
