Discuss an event/experience that shaped your world-view?

Mine was a conversation with my brother. He changed my perspective on how I see and view people. I can now tell if a person is a good influence or a bad influence. Vibes and words that they use can change how you see a person. For me, I had a so called friend who was talking about parties and drinking. He said he was just playing and I believed him. I later found out he wasn't joking and he was serious. I can now pay attention to what people say and comprehend what I am hearing. This has changed my whole perspective on the world. I am now a good judge of character and because of how I view people I know what is better for me. This is my personal experience I don't know if you can relate but I hope this helps.
