She brings her outdoor furniture inside when its winter time, Greg once asked her if she wanted him to clear her driveway of snow, she seemed to happy to see Greg because she hadn't had any guests for a long time and invited him inside and served him warm milk and food and talked. She also put everything in her backyard inside because of winter. After an hour, Greg asked her if she needed her driveway cleared, but she refused, saying that her son was going to come with his truck and do it for free. Greg then leaves mad, saying that's an hour of his life he'll never get back.
