alt Hacker NewsPrivacy feels like such an innate desire. Your mention of parents going through your room brought back a few negative emotions tied to a few memories, where my mom either came to me with something she found in my room, or walked into my room and went directly to where something was hidden and pulled it out (indicating that she had already been snooping in my room and found it). Thinking about it, I realized that's one of the reasons I started hiding things where my parents couldn't easily get to them, like in the rafters in the garage, or in various forts and hideouts I created in the neighborhood.
Privacy is in my opinion one of the most important human rights that exist and the most frequently diminished or ignored, especially around parent/kid relations. Hence why it is a part of the UDHR (universal declaration of human rights).
With regards to kid/parent relation we are often too lenient as a society. One good measurement that you can keep in the back of your head to judge a kids invasion of privacy is the following question "If this kid was suffering from abusive parents, would this allow the parent to intervene the kid reaching out?".
