Gemini is the third zodiac sign, and the symbol of this tattoo is the Twins, or the yin and the yang. In this regard, they are often practical and willing to look at both sides of an issue before making a decision. However, since they have two conflicting traits, they can also sometimes be flaky or difficult to tie down. A Gemini's birthday falls between May 21 and June 21, and they often enjoy conversation and are interested in learning more about the lives of those around them.
