I was talking about passwords with my friends, and my one friend was like, "You'd like my password because you're a South Park fan." And then he told me about the episode that he was referencing. But he wouldn't tell me the password. I didn't want to know, honestly, but I wanted to know what he was talking about. So I looked up the episode and easily guessed (and confirmed) his password. I immediately signed out after confirmation, but now I'm really curious about some things. I don't know. I don't want to risk pissing him off or letting him found out that I went on his account. Probably the only way that I would be able to refrain from going on his account would be to tell him that I figured out his password. But I think he thinks and I know our friends think that I like him already. So this would probably just further it and also make him suspicious of me. Also, I think he's about to do something stupid, so I'd like to be able to get on his private messages if need be. I don't know.
Should I tell him?
