Keating changed Todd

In my opinion, the character, who changed the most during the book, is Todd Anderson. In the beginning, he is very isolated, shy, lonely and sad. He isn´t very talkative and kind of afraid of new experiences. In the end, for me, he is one of the bravest, most loyal and strongest personalities in the whole book. 

Maybe because of his family, Todd lives very isolated and don´t want to talk with everybody or find as fast as possible friends. He lives for himself and although if he wants to try something new, he´s just to shy. But then he met Mr Keating, with who he became very close. I think at the beginning, he didn´t really like Keating much, because he "forced" him to do things, he´s normally to shy to do, like standing in front of the class and interpret a poem or scream as loud as possible. But these little things made him more open and more self-confident. 

Mr Keating taught the boys, to stand up for themselves and to not just let everything doing with them. And Todd understood, what Keating meant. At the end of the book, he stays at his opportunity, although everybody has another one. He protected his new friend Mr Keating. 

I think Todd reminded Keating a little bit of himself in his young age because he also wasn´t every time very brave. That´s because he was a little bit harder with him, to make a boy out of him, who believed in himself. And in the end, his mission succeeded.
