Callie is very proud of her brother Charlie. He's good at so many things -- swimming, playing the piano, running fast. And Charlie has a special way with animals, especially their dog, Harriet.

Charlie is like any other boy -- and he has autism.

Lisa Palmer finds herself the owner of a former post office, which has been sitting vacant for this past few years.
