Jill has a large leak in her roof, but lacks the funds necessary to repair it. Her friend Jack voluntarily makes the repair. Three months later Jill learns that Jack is short of funds; he can't pay his rent. She contacts him and says, "I'll pay the $2,000 you owe for rent." When Jack protests that he cannot accept such a large sum, Jill responds, "You repaired my leaking roof when I couldn't afford to pay for it. I now promise you something in exchange. In consideration of the roof repairs you made for me, I will pay your August rent." Does Jack's roof repair serve as consideration for Jill's promise?
