Lily's mom tells Lily about grandma's illness and Lily and Sam need to help grandma feel comfortable. Mom also says that there is something wrong with grandma's brain and it might cause hallucinations. At first, Lily isn't sure if the stories that grandma has told her are true but she concludes that the stars that grandma hid make her sick. She believes that the tiger that she met can cure grandma and decide to find the tiger with Ricky who is a family of tiger hunters. Could you please make my sentences sound more natural? Thank you for your time and help.
