Some people are just different. I’m not a body language expert but I pay attention. When Trump does these pressers and it’s noisy because of the helicopter and he cannot hear someone asking a question he does not put his hand to his ear like most people do as a signal that they cannot hear. It’s just an interesting observation another thing that makes Trump such an interesting person
