The following fact pattern should be discussed in regards to Offer and Acceptance.

Betty contracted to have her house painted. At the time, her neighbor Frank was on vacation in Hawaii. While in Hawaii, Frank received a phone call from his good friend Tom - who lives across the street from Betty and himself. He tells Frank that he likes the new color of his house. Frank was puzzled until he realized the painters had made a mistake. While Betty was at work, the painters mistakenly began painting Frank's house and not Betty's. Tom asked Frank what he wants him to do. Frank asked if it looked nice and Tom assured him it was a big improvement. So Frank said to "just let them finish - I will not have to pay for it anyway." Upon Frank's return from Hawaii, the painters come and give him a bill for $5000. Frank refuses to pay citing the contract between the Painter and Betty. He never agreed to his house being painted - the Painter made a mistake. Is this a binding contract on Frank?
