Alfalfa, a novice rock climber, decided to go on a very difficult climb. Half way up, he found himself in trouble. Darla, a more experienced climber, at great peril to herself, rescued Alfalfa from almost certain serious injury, if not death. Alfalfa was so greatful for what Darla had done that he promised to send her a check for $1,000. Alfalfa failed to send the check and Darla sues him for breach of contract. Judgement for whom? Explain.
