Thank you Inga for taking the trouble to help. I suspect your article was written pre the short mini-skirt era.
The ankle cross is a pose used by both sexes I admit. It is a male typical pose that we obviously find comfortable because we do it all the time. Etiquette is correct if its done in the way the article points out – but that’s not how a man does it – and neither do most women. No, they just cross at the ankle and unless you have excellent muscle control your knees relax to about 12″ apart! Try it!
Very ladylike! Isn’t it? Time and time again I have observed women sitting like this. Women have hi-jacked man-spreading! This position in a short skirt is a favourite of up-skirters!
