1.On May 1, 2019, Eckerly Realty Inc. mailed a written offer to Masse for the sale of an office building. The offer included an express term that: "This offer shall expire on June 30, 2019 if the acceptance was not delivered into the hands of Eckerly by the expiration date." On June 30, 2019 at 8:00 a.m., Masse sent a written acceptance to Eckerly via Masse's personal messenger. However, the messenger was not able to deliver the acceptance until July 2, 2019. On July 3, 2019, Eckerly contacted Masse, informing him that the acceptance had been delivered late, and thus refused to honor the acceptance.
