I have experienced them all. But. they were simulated. for you knew that if you ever faltered. there would be immediate help available. You and I have never known the harshness of a prison compound or a refugee camp for displaced persons. But before I lose you in a flurry of reminiscent phraseology let me say it is not the purpose of this letter to chide you for having been born free. but rather to gently remind you that your legacy has been paid for. But another advance payment is due. so that one day each of you might sit down and address a letter. "Dear Son." Now I have come to the real purpose of this letter.
