HE IS NOT A MOUSE
Description: This is a screenshot of the “Stuart Little” Wikipedia. The excerpt reads “A boy named Stuart is born to an ordinary family in New York City. He is normal in every way except that he is only just over two inches (5 cm) tall and looks exactly like a mouse”
It just stops. The story I heard about why was because the author was afraid of dying and leaving it unfinished, so he just stopped and effectively left it unfinished.
