Libras are hard to piss off, because they want to see the good in everyone and take most things in stride. They hate conflict and strive for fairness. But, like everyone, they have their rage triggers.
Whatever you do, do NOT hit these hot buttons on a Libra...
• Harming something/someone they love
• Cheating - on anything
• Lying, except little white lies to spare one's feelings
• Snubbing someone just because they aren't popular
• Physical violence or aggression of any kind
