"Where did you get that???"

I never like answering that question...especially when it is asked about a particular piece that I'd prefer not everyone and their brother (okay in this case it would be sister) wear! You know?

Take for instance this necklace:
It is similar to one I have added to my jewelry box recently. I've only worn said necklace a few times, and usually it garners a compliment or four. ;) Then, one of the compliment-ers asks "Where did you get that???" Is it bad that the compliment-eee doesn't want to respond???
