I keep thinking of you as 'Calico' but that's probably technically inaccurate. I've read about mosaicism and chimerism before but had to look up heterochromia. My curiosity is piqued by all things anomalous so it probably goes without saying that I think your eyes are arresting, beautiful, a little Liz Taylor even. Great choice of avatar.
And that was a pleasant read (intro and elaboration). I appreciate the nod to etiquette by making the post -- a preface always seems to help give a more immediate and better understanding of a book.
