Which One Are You?: Identically Different

Synopsis: Which One Are You? is a collection of short stories and poems devoted to the author's twin grandsons. The stories are inspired by observing the activities and events that, while normal for all children, are special and unique for twin brothers. The stories are centered around the theme of what it must be like for twins to encounter the natural reaction of the people they meet, wondering, "Which one are you?"

The title is credited to a childhood friend of the author, also a twin, who would respond to the often repeated question, "Which one are you?" with his own question in return: "Which one are you?"

Autobiography: Dennis Corcoran is the proud grandfather of four boys, including twin grandsons, Colin and Finn.
