What issues does the author address in Barrie's, Dear Brutus?

Dear Brutus explores what might happen if ordinary men and women, mired in unhappiness, were given the magical opportunity to remake their lives, or, as the butler Matey says, the chance to "take the right turning." The play addresses the human proclivity to blame others or fate for their failures and unhappiness, and provides the audience with penetrating insights into human nature.
