Yes. There is so much talk about body language, that I have no idea why anyone would think it a good idea for the President of the United States not to stand tall and give a firm handshake according to OUR custom. I did see a documentary on how in a political meeting, the most important man enters last with his hand on the 'visitors' shoulder. It's a sign of control. I'll look for that video and post it one day. Super interesting & I think Trump follows those psychological rules because it's part of his somewhat narcissistic personality which is a must for someone in power.
