This is very much like “Shake Hands” in its object and in its rulings. The difference lies in the kind of handshaking permitted. The rule is that the left hand only is to be used in shaking hands. At irregular intervals a whistle is blown and anyone caught not actually shaking the left hand of some other guest at that particular moment is punished in the same way in which culprits in the game “Shake Hands!” are taken care of.

Of course there are policemen, whose one object in life is to catch someone napping, or a bit negligent in the evidence he gives of a very active and left-handed spirit of sociability!
