@shellkr I heard about Linux from my grandpa (who didn't use it, but had heard about it). Eventually, I looked up linux.com and tried to find a download page. I searched for a while, but couldn't find anything. Just articles *about* Linux.
After a few weeks or months, I somehow discovered the concept of distributions, I installed Ubuntu 16.04, and began to be fascinated by every aspect of it. I became a fan of Ubuntu and was excited for Unity 8 (and was very disappointed when it was dropped).
In 2017 I began to branch out and discover other distributions. By 2018 I had tried Linux Mint, Arch Linux, many flavors of Ubuntu, Debian, OpenSUSE, and more.
It all started when I was 12, with that innocent mention by my grandpa (who still is a Windows user).
