The zodiac sign with the most severe mental cleanliness obsession: Capricorn. Capricorns are not very severe in terms of physical cleanliness, but they definitely have a mental obsession with cleanliness. Unless it's someone they like, they will feel annoyed if someone else touches them. Never provoke a Capricorn and engage in a cold war; they are inherently aloof, balancing emotions and rationality, both affectionate and heartless. The toughness inherent in Capricorns truly does not fear anyone's departure or threats; they can endure any hardship but cannot stand feeling wronged. Just one tone of voice, a gesture, or a glance that makes a Capricorn uncomfortable will lead them to silence.
