A woman contracted with a tennis instructor to provide tennis lessons for her friend as a gift. The woman agreed to pay the instructor's fee of $100 per lesson for a total of 10 lessons over the course of a month. The next day, the woman informed the friend of the gift. The friend thanked the woman and told her that she would never have tried tennis on her own. The friend immediately went to a sporting goods store and purchased a racket, tennis shoes, and various articles of tennis clothing, at a total cost of $500. She called the woman to tell her about the items she had purchased and also called the tennis instructor to make sure she had all the items she would need for the lessons. A day before the first lesson was scheduled, the woman and the tennis instructor rescinded their agreement. The friend sued the tennis instructor for breach of contract after he refused to give the friend tennis lessons. Will the friend likely prevail against the tennis instructor
