My mom is a teacher, and she was going to donate a book about experiences with angels. It was signed by the author, so she (the author) had to mail it to my mom. It arrived on a really rainy day. When she got it out of the mailbox, the package looked like someone ran over it with a truck. The package was saturated with water and the paper was torn. But, when my mom opened it up, the book inside was in perfect condition. She knew that the book and herself was being watched over angels.
