London couple Sonia and Rob have on ongoing spat all the way across the pond. "My husband seems to have issues with opening things, not finishing them, and then opening more things," Sonia says. "I don't know why he just won't finish it or throw it away." Sonia says Rob's adopted this habit with everything from milk and juice to peanut butter and toilet paper.
Rob says he likes to use things that are good as new. "If there's a fresh one that I can have or there's one that's been there for a month, I'm going for the fresh one all the time."
