Read the extract from To Kill A Mockingbird and answer questions 1-3 below.
When Boo Radley shuffled to his feet, light from the living room windows glistened on his forehead. Every move he made was uncertain, as if he were not sure his hands and feet could make proper contact with the things he touched. He coughed his dreadful raling cough, and was so shaken he had to sit down again. His hand searched for his hip pocket, and he pulled out a handkerchief. He coughed into it, then he wiped his forehead.
Having been so accustomed to his absence, I found it incredible that he had been sitting beside me all this time, present. He had not made a sound.
How does Boo Radley feel about being out of his house and in the house where Scout and Jem live?
