A not-so-hypothetical question

Imagine this: Your daughter screams for the toilet, so your husband pulls into the nearest rest stop on the highway-- a dingy, brick cell, complete with graffiti and the usual public-toilet aromas. This place is worse, though, than the usual, and your daughter refuses to place her bottom on the toilet rim because the steel cistern and bowl are not up to her (high) standards. She bucks her head and somehow in the process, dislodges your earring and you hear it clang into the bottom of the toilet. Underneath the water and God-knows what germs...not to mention urine. The earring? Nothing of consequence in material terms. Not even diamonds - 100% genuine cubic zirconias. But they are nice, and I really like them, and don't have much jewellery to call my own. So - my dilemma. To fish it out, or not to fish it out? Retrieve or flush it to it's early end? What would you do? See my comments to see what I did...
