I am currently learning C#, and I need to look for a lot of information through different webpages. However, my parents distrust me and they think I am playing computer games because almost each time they enter my room, I am switching tabs by using hot keys. When they were young, they would hide their novels(unproper) when their parents came in their rooms, and doing that is similar to what they did when they were young.
I prefer to play games about an hour per day, and my sister often "whistleblowers" that I am playing games, which makes them even more distrust me. In that case, my parents think that I play computer games every minutes when I am using my computer. I also tried to told them that I am not playing computer games every minute, include showing them the browser history and the source code I wrote. However, all of them did not work because they think I can make fake history and I can download source code from the internet. Evidences in my computer can all be fake in their eyes.
I think I do a good job of disciplining myself and I am looking for a communication way that they will trust me.
