Morrison wanted to sell a certain parcel of land to Thoelke. He decided to make an offer by sending Thoelke a letter. When Thoelke received the letter, he decided to accept. He wrote a letter to Morrison saying that he would buy the land at the price quoted in the letter. Thoelke then mailed the letter.

Before he received the letter from Thoelke, Morrison changed his mind and withdrew the offer to Thoelke. When Thoelke found out Morrison would not sell the land to him, he sued. Was Thoelke’s letter a valid acceptance, binding Morrison to the sale? Explain. Morrison v. Thoelke, 155 So.2d 889 (FL).
