In 2009, Prince Harry joined his older brother William at RAF Shawbury for Defense Helicopter Flying School. In June of that year, William, and Harry gave a rare joint interview to the BBC in which they discussed their time living together at school, with Harry joking, "First time, last time we'll be living together."
William said he was the one doing all the chores around their shared home: "Bearing in mind I cook — I feed him every day", he said of Harry. Even though Harry was supposed to wash the dishes, William said his younger brother "leaves most of it in the sink [...] and I have to wash it up," and also teased Harry for snoring.
Up until the royal wedding of Prince Harry to Meghan Markle in May 2018, William continued to tease Harry in a brotherly manner, and spoke more about his little brother as a housemate: "I hope [the marriage] means he stays out of my fridge and will stop him scrounging my food, which he's done for the last few years."
