☆Book Review---SALLY'S PHONE☆

I read a book "SALLY'S PHONE". One day, Sally and Paul exchange their cell phone by accident. Sally has a plan with her boy friend Andrew, but she cannot contact with him because she doesn't have her cell phone. Paul realize that the cell phone he has is not his cell phone, then he asked his phone number his mother, and he call Sally, and they meet to exchange their cell phone. They think "very nice", when they meet each other. Then, Sally turns off her cell phone, she go out with Paul. She throw away her boy friend, Andrew. I was very surprised because I didn't know the reason. However I feel funny, and I could find interesting the shape of love.
