It depends what they are like and what you are like... Personally I have shown my parents that I can cook, can handle responsibility and that I can be trusted so they treat me pretty much like an adult. I'm 14 so it works. To be blunt though, just show them that you won't be a <3: up the moment they leave the house, but mostly it depends on what they are like... Second to my mum, I actually do the majority of housework. My parents are from India so I don't think there's anyway to change their mind. Always thought you were older than 16 Gabe.
