People shake hands to greet each other, but how did the whole thing start?
From the BBC:
Shaking hands, which is traditionally done with your right hand, became a friendly greeting because it was proof that you came in peace and weren’t holding a weapon.
It was also a sign of trust that you believed the other person wasn’t going to take their sword out to fight you either!
I have a friend who shakes EVERYONE’S hand, so it’s great to know he never has a weapon on him.
