During the entire book, each character has been geniously crafted by JA to have his or her own very individual character, following their own agenda and, as in real life, often not being aware of how the other characters think and feel, which then of course leads to all of the conflicts. In real life it also often happens that people project their own thoughts and feelings onto others in the assumption that they will see things the same way. This can make one oblivious to the real persons feelings and thoughts.
