Fifteen days my left foot suffered, alone in it's relative completeness and normalcy. My right foot had already taken the first evolutionary step toward a big toe nail-less future. It took up less space in shoes, hurt more when I stubbed it, and didn't have to be trimmed. My left foot got jealous, poor thing. One day I woke up and it had finally put its foot down, so to speak: no more big left toe nail.
Now I have more toes without toe nails (or with partial ones) than toes with them. But I'm all matchy-matchy - three on each side - so my feet may be a bit...well used, but at least they have style. Kind of like a vintage Louis Vuitton bag.
