Right You Are (If You Think So) ( , also translated as It Is So, (If You Think So)) is an Italian drama by Luigi Pirandello. The play is based on Pirandello's novel La signora Frola e il signor Ponza, suo genero.
It premiered 18 June 1917 in Milan. The theme is conflicting versions of the truth told by the main characters, each of whom claims the other is insane. Lady Frola claims that her son-in-law Mr. Ponza went insane when her daughter, his wife, died four years ago, then remarried. Lady Frola claims he fantasizes that his new wife is his old wife. Mr. Ponza claims that Lady Frola could not accept her daughter’s death, went mad, and only survives by believing that his second wife is her living daughter. The townspeople attempt to learn the truth as the play progresses.
