Being greeted by your housemate staring nonchalantly up from the bog is, in my opinion, strangely comforting. Nothing says 'trust' like pooping with the door open. And has there ever really been a better time to ponder life's big ones? Despite the foul stench emanating from your mate's recently finalised business, it can be a wonderful moment to discuss sport, politics, and all manner of trivia. Time on the toilet needn't be time wasted.
