Iam confused. It is hard to understand brains. My grandpa had a heart attack and now his brain is making him forget what is real. He told me yesterday that he was flying a plane and it crashed. He was telling me all about it when Mom made him stop and made me go home. She is worried that it will make me scared. I told her that there are so many things in the world to be scared about and this is just one. That did not make her feel better.
