On Tuesday morning, Kumar sent an email to Harold asking whether he would accept $80,000 payable over 2 months or if not, what was the lowest sum he would take.Harold did not respond to this email and later that day, he sold the grain to Pinky. Harold sent an email to Kumar at 2.22pm that afternoon advising him that he had sold the grain to Pinky. After Harold had sent the email, he decided to check his messages and realised that he had received a message from Kumar at 2.21 pm. In this email, Kumar advised Harold that he was accepting the offer which Harold had made on Monday.
