The doctor handed me my medicine and said sorry to me because his register   had already closed. He asked if I would mind using the register at the front of the store. I told him not to worry and walked up front. One person was in line ahead of me, a little girl no more than seven with a bottle of medicine on the counter  . She held a little green and white coin purse closely to her chest  . The purse reminded me of the days when, as a child, I liked dressing myself up in my grandma's clothes. One day, wearing her large clothes and hat, I went out to buy something. I gave a fake  dollar to the shop owner, but he handed back some real coins for my purse. "Keep the change!" he told me with a smile. Now, with both hands shaking, the little girl pulled out a dollar bill and some coins for her medicine. As she tried to count her money, I could see right away that she was about a dollar short. Quickly, I put a dollar bill onto the counter. The child collected her change into her coin purse and ran out. As I walked to my car, I felt a tug  on my shirt. There was the girl, looking up at me with her big brown eyes. She gave me a smile, and put out her little hand. It was full of coins. "Thank you," she said. "That's OK," I answered, smiling. "Just keep the change!" Which of the following statements about the little girl is Not true according to the passage?
She was careful. She didn't have enough money for the medicine. She was kind. She returned the money to the writer.
