Matthew's mum and I, although we live apart, get on very well. She understands my looks, my gestures..., she can tell what mood I'm in just by looking at me; just like me, with the small difference that it's hard for me to see her gestures because of my visual impairment, but even so I can sense her...
Feedback in human behaviour is automatic. There are situations in which feedback is unconscious, the body performs its functions and, based on biological variables, seeks constant balance in favour of the functioning of the body. Now, talking about feedback in interpersonal relationships, there are also involuntary and not so involuntary responses.
Personally, all this has a cultural aspect, whether in a professional environment or in everyday life. If you travel to a Latin country and do not know the cultural aspects, you will not understand for example “la chola mata, la chiripa” or someone calling you “marico” for being a friend… You may take them as offences, and nothing to do with it.
The same thing happens if a Latin American travels to Paris, and is introduced to some friends, and when those friends, out of courtesy, go to kiss his cheeks, he would not accept it because of the macho culture that prevails in Latin America. Feedback is nourished by previous information, by lived experiences.
