Your older sister (22), you're 17 M/F. Your mum always told her she's not supposed to clean her ears or eardrums with Q-tips, but her ears produce a lot of earwax. While you 2 are talking one day, she turns her head away from you, and you can see inside of her right ear canal, it's full of earwax. You know you should use some Q-tips and help her clean out her ears.
