Note 65 — 57. Correct Usage—I am not[65]
Reading edition
Note 65 (page 141). By having another pupil stand before the class and speak for the pupil who is a bird, flower, or animal (replying, for instance, "No, he is not a dandelion" or "Yes, he is a sparrow") the game I am not is easily transformed into the game He is not. Similarly, the games He has not and He does not may easily be devised.
