Scouts greet each other in a special way. They always shake hands with their left hand. The origins of this custom come from when Baden-Powell was a soldier in Africa. He saw lots of tribal chiefs who carried spears and shields. He noticed that it was a sign of great trust to offer your left hand when shaking hands. This is because if you shake with your left hand you will have to put down your shield while the other person still has a spear in their hand!
