Strengthening the crossing of hands

If a person not only crossed his arms over his chest, but also clenched his fists, such a chain of gestures immediately betrays the hostility and sense of smell of the interlocutor. If, at the same time, he smiles with clenched lips or clenches his teeth and turns red, then a verbal or even physical attack may well be expected. It would be more reasonable in such a situation to find out the reasons that gave rise to it, if, of course, they are not obvious. The person in this position obviously has aggressive feelings towards you.
Arms are crossed on the chest, fists clenched - there are all signs of hostility
