I do write notes from Santa and also the tooth fairy. I actually forgot one night to replace the tooth with some money, my daughter was so upset in the morning. I told her to put the tooth back under the pillow the following night and see what happened. I had to write an apology letter from the "tooth fairy" explaining that she had been too sick to fly the previous night, but was feeling much better. Her face lit up the next morning as the "tooth fairy" had left some extra money to make up for "her" mistake.
