'Who was that, G---?' 'I don't know.' 'Then why did you do that?' 'Because I saw he thought he knew me and was expecting it of me. If I hadn't done it he would have been hurt. I didn't want to embarrass him before the whole street.' 'Well, your heart was right, G---, and your act was right. What you did was kindly and courteous and beautiful; I would have done it myself; but it was a lie.' 'A lie? I didn't say a word. How do you make it out?' 'I know you didn't speak, still you said to him very plainly and enthusiastically in dumb show, "Hello! you in town? Awful glad to see you, old fellow; when did you get back?" Concealed in your actions was what you have called "a misleading reservation of an explanatory fact"-- the act that you had never seen him before. You expressed joy in encountering him--a lie; and you made that reservation--another lie. It was my pair over again. But don't be troubled--we all do it.'
