heart-to-heart talk, a

A confidential, intimate conversation. This expression, which implies that two persons are opening their hearts to each other, in fact often refers to a conversation in which one is warning or reproaching the other. The term dates from about 1900 and was sometimes abbreviated, as in S. E. White’s Rules of the Game (1910): “Let’s have a heart-to-heart, and find out how we stand.”
