What is it about opposite signs?

The sun sign opposite of ones sun sign is usually highly stimulating and enjoyable. The reason for this is when signs are in opposition ( like your wonderful examples) it is like whatever one lacks in their nature, the opposite sign can deliver. That is what an opposition does. It always involves another. Two people. Both with certain qualities and are attracted to those that have the qualities that they lack. Leo loves the limelight. Aquarius could care less. Sagittarius loves the big picture. Gemini sees all the details. Aries is a warrior. Libra professes peace and mediation. Taurus loves the outer beauty in life. Scorpios seeks the darkness in life. And there you go. Each fulfilling a lack in their nature. How many times have we heard opposites attract? Well, they do. They really do. Good question. Good luck and bless you.
