Now entering a post-truth era? Messenger Mercury spins retrograde today, reverse-commuting through Sagittarius and your ninth house of honesty and candor until December 15. Telling fact from fiction won't be easy for the next three weeks, so just don't plan to take anything at face value. During this time, your fuse may be shorter, making it easier for people to push your buttons. If you're feeling triggered or reactive, take a timeout because a fiery discussion could become an incendiary debate—one that has potential to burn an important bridge. Travel could get gnarly if you don’t plan with care so as to avoid any snafus.
