Teaching my son to shake hands like a man

Been noticing a lot of young guys have weak handshakes these days. Decided to sit down with my 12 year old and teach him the right way. Firm grip, look em in the eye, say their name back. He thought I was being too intense about it at first but I explained that a handshake is your word before you even speak. You only get one first impression. Caught him practicing with his grandpa yesterday and felt pretty proud about that.
