You'll support your friend, and in turn, they'll bring excitement and fun to your life. Warmth and affection will run between you. This friendship will be based on mutual good feelings, but also on your complementary qualities -- and maybe even an element of sexual attraction.
You'll develop a real friendship and give each other a lot of attention; you'll hug a lot and really let each other know how much you like each other. You'll just make each other feel good. You'll probably have a fun and active social life, more due to your influence than your friend's, but they'll bring along their own brand of enthusiasm, which will be the strength and dynamism that you might lack at times.
