Nurse: Come out the door. He's holding the door for you. (Indicating my son.)
Elderly man: Why should I come out the door?
Nurse: Because we are going for a walk.
Elderly man: Where?
Nurse: Just around the block. [He passes through the doorway.] Now, put your hand on the railing.
Elderly man: Why should I put my hand on the railing?
Nurse: So you won't fall.
[He puts his hand on the railing, but stops moving. My son continues to watch in fascination.]
Nurse: Now step down, step down!
Elderly man: Why should I step down?
My son: You should step down because the time has come for the people of Uganda to be free!
