Dear Aunt Cassi,
Do you remember the little toy train I left at your house in May, the train my Mommy got for $5 at the train museum, the train I haven't mentioned in two months? I really need it now. I have frantically searched all my belongings and was very worried until Mommy reminded me that it was at your house. If you could mail it too me very soon, I would be oh so grateful. I am lost without it.
