Quote 1
And she said, "Are you telling the truth, Christopher?"
And then I said, "I always tell the truth."
And she said, "I know you do, Christopher. But sometimes we get sad about things and we don't like to tell other people that we are sad about them." (109.10-12)
You might recall that Christopher has a similar conversation with the policeman at the beginning of the book (31.23-24). So what makes this one different? One thing is Siobhan's "I know you do, Christopher," assuring him that she trusts him, and knows he doesn't lie. But what she goes on to say, about the way we often conceal our feelings and keep things hidden, reminds us that this is precisely the sort of thing Christopher is incapable of doing.
