Recommended for ages 6+. On their first day of first grade, Tim tells Mike he is moving to another city. Tim shows Mike his spectacular new penknife, a going-away present from a neighbor. Accidentally pocketing the knife, Mike is too late to return it the next morning-Tim is already gone and his house is empty. Mike's ingenuous but determined efforts to return the knife to his best friend are both funny and touching, demonstrating the clever workings of a six-year-old mind and the lengths even a young child will go to for a true friend.
