An 18-year-old woman from the United Kingdom has unintentionally gone viral after she shared her new finding on social media.
While changing out her duvet cover, the teenager realised that when buttoning up the duvet, you should do the buttons back to front so that you can't see them.
While she thought she was just very behind on the times, it seemed a lot of people from all sorts of generations had never thought of doing this 'hack' either!
