A childhood belief about imaginary friends

There used to be these realistic plastic toy horses by a company called Breyer that little girls loved to collect. My friend Mary was convinced that her Breyer horses had souls and would move around and do stuff when we were out of the room.One day she left a pen and paper and asked the horses to write a message. Later, we found strange markings on the paper, like another language, and it gave us both chills.We were absolute believers!Years later, her brother admitted he had written the mysterious message. Mary was very hurt though she was in her 20's.I think this experience had been very real and special to her, and he ruined the magic.
