Haddon suggests that we must learn to accept the parts of people we dislike or find hard to understand, for it is only when we embrace the weaknesses and struggles of others as well as that of ourselves, that we are able to confront and overcome them.
" 'What the fuck did I tell you, Christopher?'This was much louder.... 'Except I haven't done any of those things. I just asked Mrs.Alexander about Mr.Shears because..' But Father interrupted he and said, 'Don't give me that bollocks, you little shit.'" (Haddon 81)
"You have to learn to trust me...And I don't care how long it takes...If it's a minute one day and two minutes the next and three minutes the next and it takes years I don't care...This is more important that anything else..Let's call it a project. A project we have to do together." (Haddon 219)
"Father nodded and he didn't say anything for a short while...'thank you.' Then he said, 'I'm very proud of you, Christopher. Very proud." (Haddon 215)
"I know I can do this because I went to London on my own, and because I solved the mystery of Who Killed Wellington? and I found my mother and I was brave and I wrote a book and that means I can do anything" (Haddon 221)
