A lot of information can be gleaned from astrology about a person, including how they deal with emotions. You can learn a lot about your friends, family, and even yourself by seeing which zodiac sign is the least emotional.
Among all the zodiac signs, Aquarians are the least emotional. Their perspective on emotions is different, and they definitely experience them, but they are more detached from them.
Rather than wasting time on emotions, Capricorns focus on their own goals. Despite feeling their own emotions, they do not feel the need to express them.
It's generally not an issue for Geminis to let emotions stand in their way of being friendly and social. Their forgiveness and forgetting skills are unmatched, and they never hold grudges.
They don't let negative feelings get in the way of their happiness, and they tend to be pleasant people as well. Despite getting bummed out every once in a while, they have a tendency to always look on the bright side of things.
It is more common for Libras to match others' emotions rather than express their own. Regardless of what it takes, Libras will maintain peace even at the cost of burying their own emotions.
Virgos feel emotions pretty intensely, but they understand and work through those emotions extremely well. It's almost always possible for them to turn a bad situation into a learning opportunity, so they'll rarely wallow in negative feelings.
