Carter Morley and Erena Erickson live side by side in town homes joined together by a shared wall. Both residences are in need of new exterior paint. On Monday, Morley calls a painter. Tom Sizemore, having selected his name from the classified section of the phone directory. Morley describes his address, the physical dimensions and structure of his home, and he agrees with Sizemore that the work will be performed that Friday. Sizemore estimates that with his crew of five, and given the relatively small size of the home, the work will only take one day to complete. Morley advises that although he will have to work a fourteen-hour day on Friday, he would like to have the work completed in his absence. In passing conversation with his neighbor Erickson, Morley advises her of his home improvement plan.

Early Friday morning Sizemore and his team arrive at the address, but by mistake, they began work on Ericksons side of the building. Although Erena is home, she does not object to the work. Nor does she inform Sizemore and his crew of the mistake. Midway through the day, she offers them fresh-squeezed lemonade and ham sandwiches, and they heartily accept.

Upon completion of the work at 7:00 pm, Friday evening, Sizemore knocks on Erenas door and asks id the man of the home is present. That he would like Morley to review the work and pay the agreed-upon price for the work. Erena chuckles and breaks the news that the painting crew has made a mistake, one to her benefit. Erickson proclaims I do not owe you one dime, because you do not have a contract with me; I will give you ten minutes to remove yourself and your materials from my property. Or I will call the police.

Do Erickson and Sizemore have a contract? If so, why? If not, are there any other theories of recovery available to Sizemore?
