As I was reading today, I noticed that Clay keeps saying "It's just a school project." When his mom asks him what he is doing. He was searching for the location on the map that Hannah told him to go to when he ran into his mom, and she kept asking where he was going. He continued to respond with those simple words, "It's just a school project."
   I think that is the most important line in that chapter because no matter how hard he wants to tell his family and friends what he's doing, he keeps it a secret. He is so caring for Hannah that he can hide everything from people, no matter how bad it is eating him up inside, and that is something you love to see in a character, which allows you to look up to him.
