I know a little boy in my village whose friends called the nickname "2 Face" because his face (and of course his whole body) was divided into two halves of slightly varying pigmentation. I wonder if he was battling with autoimmune issues as he proudly answered his nickname.
Nature is indeed very flexible and there doesn't seem to be a limit to the possibilities. Thanks for sharing. Worth reading.
I hope 2Face gets to grow old with his face. I have never seen anyone with the condition or I may have but just did not recognise it for what it was.
Thanks for your comment. The nickname is apt.
