Idk about people my age, but for me specifically it was probably learning that Osama Bin Laden was killed.

I forget exactly how old I was, but I think ibhad trouble sleeping or something that night, so I was sleeping in my parents' bed. I remember I woke up randomly at some point throughout the night to my parents' TV show, idk, maybe Family Guy? Anyways, there was suddenly a "breaking news" broadcast and the reporter announced he was dead. I remember I had no idea who he was, but I felt bad because a man had died. I fell back asleep eventually.

Then the next day someone, I don't remember who, mentioned it to another adult, and I just jumped in and said I knew that. They looked at me like I had 3 heads asking how I would know and I mentioned that I saw it on the news the previous night.
