Have you noticed what useful lessons you may receive through a shrewd look at the faces of the people you come across in traveling?
You will see stinginess;
pluck and nervous fear;
wisdom and simplicity.
You will notice the drinker and the abstainer;
the hopeful and fearful;
the clever talker and the bore;
the flighty and the modest;
the pilferer and the honest fellow;
the loafer and the worker.
Five minutes in a tramway car may offer us many lessons if we care to take them.
