Read the letter and answer the questions that follow.adapted fromA Letter to His Sonby Robert E. LeeRobert E. Lee was the general of the Confederate Army during the Civil War.You must be frank with the world. Frankness is the child of honesty and courage. Say just what you mean to do, on every occasion, and take it for granted that you mean to do right. If a friend asks a favor, you should grant it, if it is reasonable. If not, tell him plainly, why you cannot.Never do a wrong thing to make a friend or keep one. The man who requires you to do so is dearly purchased at the sacrifice. Deal kindly but firmly with all your classmates. Above all, do not appear to others what you are not.If you have any fault to find with anyone, tell him, not others, of what you complain. There is no more dangerous experiment than that of undertaking to be one thing before a man’s face and another behind his back. We should live, act, and say nothing to the injury of anyone.Nearly a hundred years ago there was a day of remarkable gloom and darkness. The light of the sun was slowly extinguished, as if by an eclipse. The Legislature of Connecticut was in session. The members shared in general awe and terror. Someone moved an adjournment. Then there arose an old Puritan who said that if the last day had come, he desired to be found at his place doing his duty. He moved that candles be brought in, so that the House could proceed with its duty.There was quietness in that man’s mind, the quietness of heavenly wisdom and inflexible willingness to obey present duty. Duty, then, is the sublimest word in our language. Do your duty in all things, like the old Puritan. You cannot do more; you should never wish to do less.2Read these sentences from the letter.There is no more dangerous experiment than that of undertaking to be one thing before a man’s face and another behind his back.
