Question: Visca, while visiting a friend's house, was injured when some heavy ceiling tiles in the bathroom came loose, fell, and hit her squarely on the head. She suffered a slight concussion. Her friend gave her money to see a doctor and to pay for the prescriptions ordered by the doctor. In turn, Visca agreed orally not to sue her friend for the injury she received. Several weeks later, because Visca complained of severe headaches and had to make several more visits to a doctor and continue with medication, she decided to sue her friend for additional expenses and pain and suffering. Can Visca recover the additional money?
