Confession: I was once in a sort of yandere-like relationship with another girl on the internet. Don't get me wrong, it was never my intention for go for anything more than friendship, but I guess I accidentally escalated things with her. Like, whenever she would talk about how much she hated her life, family, etc., I'd go in and play the sympathetic nice-guy role to sorta bring her mood back up. But whenever I go a little while without talking to her, she would either speak to me irritatedly, or she would speak erratically. Whenever I ended the conversation, she'd give me some cheery statement, a crapload of smileys, and urged me to not make her wait too long again. Eventually, I could no longer handle talking to her, and I told her I didn't want to be friends anymore. She went into an all-caps ragefest with me, and it was scary as all hell. It took me a good 20 seconds to recover from my initial reaction and block her messages.
I learned two important things from that encounter. Firstly, don't ever use Chatango again. Secondly, be careful with who you act nice with. Thank god I didn't know her IRL.
Good thing I'm not a girl~
