Gracie and Luke love to tattle on each other. They aren't mean about it, or even annoying. They just like to be reassured that they know and understand what is nice/good behavior and what is mean.
One day, Gracie and I were sitting reading a book, when a cry of distress came from the bathroom. Gracie went to go investigate and when she came back, she had quite a story to tell me. Not believing her, I decided to check it out for myself.
