Confession: I am a collector of things. I have a hard time parting with random people’s business cards, clothes I haven’t worn in years, and even pens. A new survey by classifieds website Kijiji.com found that 81 percent of couples view unused items lying around the house as a source of tension in their relationships. In the survey, 27 percent of men and 17 percent of women say their partner’s clothes and fashion items cause the greatest conflict. I suppose this is as good a reason as any to clean out the ole closet.
