I feel like when people are upset when they've been lied to in games

It's probably because some or a few don't even know or watch survivor or big brother, especially in island, outcasted, hysteria, or a frenzy. Some people take things FAR too seriously when people who aren't your closest allies lie in games. You're not gonna be losing your best friend over a game. You're not going to be feeling like your career is over because of that one low placement. That's why they're so many chances.
