Random question: ever met/seen a girl with a birthmark in her eye b4?

This is weird. I was a preschool teacher for 7 years and we were having pictures done. I saw a dark spot on the white part of a little girl's eye. The other teacher and I looked at everyone's eyes and their were dark spots on the white's of all the African-American children's eyes. Birthmark? I think so! Her eye is cool looking though!
