"It seems to me that almost everything is a waste of time," he remarked one day as he walked dejectedly home from school. pg. 9

Without stopping or looking up, he rushed past the buildings and busy shops that lined the street and in a few minutes reached home—dashed through the lobby —hopped onto the elevator—two, three, four, five, six, seven, eight, and off again opened the apartment door —rushed into his room—flopped dejectedly into a chair,
and grumbled softly, "Another long afternoon." pg. 11
