When the conversation or the interlocutor really interests us, we put one foot forward to reduce the distance between us and the interlocutor. When we are not interested and miss, then we put our foot back, and if we sit, then we hide it under the chair.
The man is clearly interested - he put his foot forward and shows the groin area. The woman is either not passionate about them or has not yet determined her attitude.
In the figure we see that a man is trying to demonstrate his interest with the purely masculine body language signals available to him. He put one foot forward, spread his legs, showed the groin area, and spread his elbows to appear larger.
The woman, it seems, is not too interested in the interlocutor. Her legs are close to each other, her arms are crossed - she tries to occupy as little space as possible. Apparently, the man for nothing loses time.

Summary

Our feet silently tell the interlocutors about where we want to go and whether we like the conversation. In a business setting, women should not cross their legs in a sitting position, unless they are wearing a long skirt. The appearance of female hips is able to excite almost any man, after which he will cease to pay attention to what the woman tells him. Men remember that they talked to a business woman, but if she was wearing a mini-skirt, they would never remember what she said. Many women wear short dresses and skirts in a business setting, since it is this kind of media that promotes the media. Over 90% of television-leading women appear on screens in short dresses, showing long legs. This is because at the sight of such a woman, male viewers are in no hurry to turn off the TV. However, studies show that the more women have visible legs, the less men remember her words. The rule is very simple: at a party it is quite acceptable to show crossed legs, but in a business setting this should not be done. Men should also adhere to certain rules in a business setting - in particular, keep their knees closed.
