Gabe Mollica begins his critically-acclaimed off-Broadway show "Solo: A Show About Friendship" with a declaration: "I turned 30 and it occurred to me that I don't have any friends."

Over the next 70 minutes, Gabe dives deep into what it means to have friends in your 30s, his special relationship with Stephen Sondheim, working at a summer camp for children with chronic illnesses, and what happens when you break up with your best friend.
