I was out and about (drab) the other day doing what we've all been told to do and that's observing GG's. While doing so I realised there was a GG doing what I'd seen many others do but never really been conscious of. Namely holding one arm up across the chest so that the hand lays on the top of the chest bone such that fingers point to one side of the neck, the thumb to the other.
I realised I'd seen GG's do this so many times before. Sometimes when window shopping or just browsing, other times while in conversation, often while listening to another's bad experience. A sort of, "I feel your pain" gesture.
So I guess that's just one more subtle nuance I need to add to the repertoire of femme gestures.
