Jimmy, an art dealer and merchant, is running out of funds. Luckily, he owns a priceless Van Gogh painting. He writes his friend Tommy. The letter says “Tommy you remember that Van Gogh painting you were interested in buying? I will offer it to you for $500,000. I will give you one month to accept this offer.” Jimmy signs the letter. Tommy receives the letter, and he is very excited. He writes back two weeks later saying that he accepts, and Tommy encloses a check for $500,000. Unfortunately, Jimmy received a better offer for the painting, and Jimmy accepts that one.
