In May, Rebecca's daughter, Isabella, sustained a serious injury that made it impossible for her to continue living alone. Isabella, who is a novelist, moved back into Rebecca's home after the accident. Isabella has begun writing a novel based on her recent experiences. To accommodate Isabella, Rebecca incurred significant remodeling expenses (widening hallways, building a separate bedroom and bathroom, and making kitchen appliances accessible to Isabella). In addition, Rebecca had an indoor swimming pool constructed so that Isabella could do rehabilitation exercises prescribed by her physician.

           In September, Isabella underwent major reconstructive surgery in Denver. The surgery was performed by Dr. Rama Patel, who specializes in treating injuries of the type sustained by Isabella. Rebecca drove Isabella from Champaign, Illinois, to Denver, a total of 1,100 miles, in Isabella's specially equipped van. They left Champaign on Tuesday morning and arrived in Denver on Thursday afternoon. Rebecca incurred expenses for gasoline, highway tolls, meals, and lodging while traveling to Denver. Rebecca stayed in a motel near the clinic for eight days while Isabella was hospitalized.
