An Aquarius is a passionate, quirky, sometimes quiet and shy, and sometimes outspoken and temperamental human. They're deeply compassionate for humanity, equality, freedom of expression, and intellectual conversations. As an air sign, they value mental stimulation above most other things. The Aquarius may appear aloof, but as highly sensitive people, they just require a little more time to warm up. These free-spirited, imaginative, and slightly inconsistent people thrive when others can relate to and respect the many sides of their personality.
