Butterfly effect.

In our lives, events happen: ups and downs. It is they that make us who we are. However, if you think about it and trace this chain of events back to the past, you will find that the root cause was either insignificant or, at first glance, had nothing to do with it. I want to give an example of a chain of events that led me to the Hive: If I hadn't transferred to another school in the 9th grade, I wouldn't have met Maria, a classmate who persuaded the girls in the class to install a mail agent. Without the mail agent, I wouldn't have met Lesha, and anime would have remained a small hobby instead of becoming a passion. If I hadn't watched a lot of anime at the time, I wouldn't have started watching anime online. While searching, I wouldn't have clicked on a link to a browser game, and then I wouldn't have moved from that browser game to the forum of the same game. Out of laziness, I signed up for a game. If there hadn't been all sorts of jerks, with whom I had many arguments and disappointments, I wouldn't have started looking for another Mafia forum and wouldn't have ended up on Heroes, and I wouldn't have met so many good, creative, and interesting people. This is not a complete chain, but I am giving it as an example. What chains of events have you experienced in your life? What was the root cause of any current events?
