Shortly after coming to this site I posted one of those threads. The first response I got was quite insulting. Only an ignorant redneck would think this is ok or some such noise bathe rest of the replays were much kinder but all pointed out their reasons for not wanting to be approached.
The more I learn about myself and you ladies the more I understand. Obviously A didn't mean harm. I suspect she was operating from a desire to help as well as the desire for social interaction. The story implies, to me at least, she was uncomfortable and had to work up her courage to come talk with you. I'm glad her faux pas didn't cause you great discomfort. I'm also glad you were able to remain civil with her.
In my entire life I have only noticed maybe half a dozen people put in public. I know I never did malicious harm, I sure hope I never caused unintentional harm or made anybody uncomfortable. It's a shame the world is as it is.
