As one whose taste in mental states has always run toward the coma, I have very little patience with the current craze for self-awareness. I am already far too well acquainted with how I feel and frankly, given the choice, I would not. Anyone who is troubled by the inability to feel his or her own feelings is more than welcome to feel mine. It should not be surprising, then, for you to learn that I am something less than enchanted with a concept such as mood jewelry. For those of you fortunate enough to have your lack of awareness extend into the realm of advertising, mood jewelry is jewelry that tells you your feeling via a heat-sensitive stone. And although one would think that stones would have quite enough to do, what with graves and walls and such, it seems that they have now taken on the job of informing people that they are nervous. And although one would think that a person who is nervous would be more than able to ascertain that fact without the aid of a quite unattractive ring, this is apparently not the case.
