I often find that imperfections make things more rare and real. I actually love the imperfections of the people I love, the crinkles along the eyes, the wrinkles, the birth marks, the scars. It's what makes them rare and real.
I have a pretty elaborate birth mark on my ankle. I've had it my whole life. When I was little I used to try to wash it off because it looks sort of like a smudge of dirt except that it has 20 or so freckles in it. My dermatologist told me it was called the constellation because, I guess, in a way, it sort of looks like one. My very sweet mother forgets about it though and tells me to wash it off when she notices it. For me that has always been a little hard because I keep inventory on the details/imperfections of the people I love and it's a detail she always forgets. It's okay though, sweetness is her strength, not details.
I look for rarities not perfections. I think the array of characters in my book reflects that aspect of me really well. And I hope other people love them as much as I do.
