"I walked with my friend to the news stand the other night and he bought a paper, thanking the newsie politely. The man behind the counter did not say a word to acknowledge him.
‘A sullen fellow, isn't he,' I commented.
‘Oh, he's always that way,' shrugged my friend.
‘Then why do you continue to be so polite to him?'
‘Why not?' inquired my friend. ‘Why should I let him decide how I'm going to act?'
As I thought about this later, it occurred to me that the important word was "ACT." My friend ACTS toward people--most of us REACT toward them."
