Got this from my dear friend Carol's youngest daughter, about her youngest daughter:
Ellie is now able to read your books. She loves them! Awful Waffle makes her laugh and laugh! She was especially thrilled to discover the author had signed the book for her, and the author was a special friend of grandma Carol. (She was only 3 when you sent them so she had completely forgotten.) Just wanted to thank you for your beautiful stories, they are loved and appreciated!
We writers endure a lot of rejections and hurt feelings, but notes like this make being a writer the best job on Earth!
