Deaf to the Voice of Wisdom ?

It was definitely one of those "Oh Drat!" moments,  I had lost an earring and I wasn't even wearing earrings! 

 Those of us who make and sell jewelry are familiar with the standard,  black velvet  necklace display easels, they're not high-end but they're affordable and easy to transport as they neatly, fold flat.

Recently I fabricated a simple chain necklace and then fashioned a pair of cute matching earrings -- these I arranged upon a flat necklace easel and then - later in the week - I decided to bring some items to a small gallery that sells my work.

Well I think you can see where I'm going with this.  My brain told me I should either remove the jewelry from the easel or place easel, with it's jewelry attached, into a large clear plastic baggie, but did I listen to my own logic ?  Nooooo !  

Somewhere, between my home and the gallery (and back again)  one rebellious earring made its' escape.  Where it is I'm not sure, however I am fairly sure I will never see it again. 
Could I make another earring to match the orphaned one? Maybe, but getting the lengths of the headpins to match may be difficult as I didn't take notes as to how long I made the shorter headpins . . . nor do I have more of those lovely 8 mm gold filled, soldered jump-rings that attach the dangles to the earring hook . . . not to mention I don't have enough of the Swarovski 4mm, bi-cone Fire Opal Crystals.     So drat, Drat and DRAT !!!
Oh why don't I learn to, not just listen to the voice of wisdom, but to actually DO what it tells me I should ?
