One of These Things is Not Like the Other

I've noticed this new nail polish trend lately on several people - a different color on the ring finger only.  This looks kind of cool and, being the trendy gal I am, you know I will try it.  However, to me this hearkens back to the 70's and 80's when the only time you saw a different colored nail on a ring finger was when you were talking to a coke addict!
