I was watching a video about an app I play and it gave a spoiler warning. I was like "I'm far enough in the game, I should know what this is." Turns out I wasn't that far in the game and I spoiled myself- one of the main characters was killed by another character. I was mad, but then again, I did that to myself. Anyway I got to that point in the game and I was still sad, even though I knew it was coming.
