That was... odd.
As jmaynard and I were walking a bit downtown after supper we heard someone behind us say, "Sir?" and we both stopped, a bit surprised as we hadn't expected to be addressed at all, let alone rather formally. The young lady who got our attention said she just wanted to say how nice she though my hair was. I thanked her, and she apologized for breaking the stride of our walk and repeated and repeated that she thought my hair was nice. I did not tell her that I do nothing special with my hair. It just is the way it is.
