I have a slight asymmetry and when I'm walking in a crowd like a shopping centre or something I feel that people might be paying detailed attention to the back of my head. Although the only person who has said something to me is my mum and that's obviously cos she's given birth to me. But my mum pays alot of attention to people and their physical features. Maybe the thought that people are paying alot of attention to my detailed features is just a thought in my own head and that's all it is!
