Greetings friend @joseph1956, there are times when people judge other people or qualify them by their behaviors, everyone lives their lives in their own way, in my case in particular I believe that these situations are given by some bad experience of the past and the person is marked by that situation hence it is limited to do things that for others are common, I have a friend who does not give the greeting with a handshake simply says hello, and that's why they reproach him.

Very good article leaves an interesting message.
