I wondered about this too. Some people have moles on their faces, some are born with pigmentation. I wouldn`t say I am better than some shallow individuals we all seen. I am sufferer, but I am also a sinner. If I see someone with mole/marks/scars/acne I will notice it, and I will spin whole life story of that person in my mind. Though I am not the type to look back on the street at someone of different race, point finger to someone in a wheelchair or smth other. I am good at giving the impression "I didnt notice, I dont care, busy to go do my own stuff". If acne has tought me anything: dont boost your ego on other`s misfortune. I wasnt the type to do this (as far as I remember), but, yeah...
