Miller listed her home for sale. On August 4th, Norman made an offer, specifying that it must be accepted by 5:00 p.m. on August 5th.

Miller then revoked the counteroffer to Norman. But right before 5:00 p.m., Norman initialed Miller's counteroffer and delivered it with a deposit. To whom, if anyone, did Miller sell her home
