It's hard to see mine, due to the curly wurly nature of my hair. But, if I part my hair, it likes to sit slightly off centre, to the right. I also have a cow's lick, which is at the front right of my head. This isn't noticeable, because of the curls, but could be seen when I had a fringe (bangs).
My curiosity was roused by this and it's possible connection to ASDs, so I've googled it a bit and was reminded of someone. There was a little girl in my daughter's nursery class with a double crown, which was really noticeable. The head teacher knew I spoke to the girl's Mum and asked me if the little girl spoke, as she had never heard her speak in nursery. She did speak, but not in complete sentences and she spoke very quietly, in a very babyish voice, and I couldn't understand anything she said. I wonder now if she was investigating if the girl might be on the spectrum (she never mentioned the double crown BTW). The Mum was very shy and the only person she ever spoke to was me. At least, I assumed she was shy, but come to think of it, she probably was on the spectrum. I invited her to my house for a play date and hoped she'd relax, with it just being us there. But, it was uncomfortable for me, when I'm usually good, on a one to one basis. She seemed to be really nervous, but I'm sure she was struggling with the conversation.
