Curveball The Year I Lost My Grip

This week, I'll be doing character analysis. The character I'll be analyzing will be, Peter. He is the main character of the story, as you might recall from the last blog. I wrote about his personality, and a little about what the story is about.
Peter seems to be really, there really is no words to describe this... The only thing I can kind of think of for it is, disconnected from his feelings. I know that with him being injured, and not being able to ever pitch again, it will have some serious damage to his emotions since he enjoyed baseball so much. One of the things that keeps standing out to me is when he says how bad his elbow hurts from the surgery, and how he wants to cry, and how much he misses playing baseball. Peter holds back his emotions, in my opinion. Another thing, probably the biggest one, is how he didn't tell anyone at all, not a single soul, how bad he was really hurt in the first place, just so he could continue playing baseball. He also doesn't tell anyone, especially his best friend, AJ, that he can never play again. AJ always tells Peter things like, "Don't worry, everything will get better when you can start playing again." Peter's excuse for him not telling AJ about this is that he thinks he won't be his friend anymore. He thinks AJ will just leave him, and forget about him, only because he can't play anymore.
The second subject, or topic, I'll be doing this blog is Tough Questions. I immediately thought of Tough Questions when I was reading last night. Peter's grandfather is showing early symptoms of Alzheimer's disease, according to his new friend, Angelika. He turns to her, late one night when he has no one else to talk to. He explains to Angelika how earlier that day, his grandfather had called him twice. He missed the first phone call, but answered the second. His grandpa had called to ask Peter to come over, because he has fallen. When he rushes over to his house, his grandfather tells him to not tell his mother (which is his daughter) about the incident. Peter called Angelika to ask her what she would do, and what she thinks would be the right thing to do. Peter knows how important his grandfather's health is, especially how serious falling is in elders. At the same time, though, he doesn't want to betray his grandfather. This is a really tough spot for Peter; I would imagine it would be for about anyone who is really close to their grandfather, like Peter is.
I'd like to think if I was Peter, I would tell my mother. I know that I told my grandpa I wouldn't, but some things are just too big to keep secret.
