Battle of the loo is dirtiest home truth
One-in-three people who share living space with family members or friends say the bathroom is the single-biggest battlefield in the house, with arguments regularly raging over whose turn it is to scrub the sink and defumigate the loo.
Loading and unloading the dishwasher is the next most common cause of conflict, followed by vacuuming, cooking and washing dishes. Least contentious of the dirty dozen detestable duties are hanging out washing and sweeping the floor — presumably because the former gets you out of the house and the latter arms you with a potentially intimidating weapon.
