Lesson 22-1 Byheart
Some plays are sosuccessful that they run for years on end. In many ways, this is unfortunatefor the poor actors who are required to go on repeating the same lines nightafter night. One would expect them to know their parts by heart and never havecause to falter. Yet this is not always the case.
A famous actor ina highly successful play was once cast in the role of an aristocrat who hadbeen imprisoned in the Bastille for twenty years. In the last act, a gaolerwould always come on to the stage with a letter which he would hand to theprisoner. Even though the noble was expected to read the letter at eachperformance, he always insisted that it should be written out in full.
