Paul contracts to sell his home to Dee for $100,000. The sale, which was negotiated by a broker for the two parties (Paul and Dee) who never met, was set to close on September 1. On July 15 (before the closing date), Paul discovers the identity of the buyer, and immediately writes Dee to tell him that there's no way he'll ever sell his house to "some hippy." Does Dee have to wait until September 1 to sue Paul for breach of contract?
