This may seem strange but watching the Queen's funeral reminded me of something I have been curious about. For background I am a woman, over 60, my mother died young and my father was unsocial to say the least. Relatively recently I noticed that many if not most women automatically reach behind and make a smoothing motion over their hips and thighs when sitting down even when wearing trousers. I have only become aware of this from watching television hence my mention of QE's funeral coverage. I notice Charlotte did it on getting into their car on leaving the funeral and her mother also. I honestly have no idea if most women do this in daily life or how they know to do it. Presumably taught by mothers/female relatives but has it always been so? I mean were others my age consciously taught and passed it on or has it developed more recently? I never understood about handshaking either: when and how to do it, who starts and finishes it , why so much significance is assigned to it.
To be clear I am not worried about this just curious if parents generally consciously teach such niceties and how they know how to do it.
