By Mark Haddon

Chapter 109

  • Christopher writes some more in his book and then brings it into school so Siobhan can help him make corrections.
  • When she reads the bit about his mother and Mr. Shears, she's understandably shocked.
  • She asks Christopher if this news made him sad. (No.) Is he sure? (Yes.)
  • Siobhan explains that sometimes people don't like to admit they're sad, or don't even realize they're sad. And even when he insists he's not sad, she tells him she's available to talk if he wants.
