Storm and Calm
In most cases she is a storm and he is calm. He is a man and he is a giant of his and her life, he is the best shelter for her and he knows that no one can care about her the way he can and he knows she needs this care and protection of him. Though, the permanent tension drives people mad and they need to have a rest from this tension.
And she is the way he has his rest. She is a storm and she is not that serious and steady like he is. she never stays at one place for a long and she always wants him to be with her and she always takes him away from that tension to some place else where he can forget bout all those duties and troubles and can feel this life the way she feels it.
She is like a fresh air for him and there is no way for him to live without that fresh air. But she is too light-minded to survive in this world and he is her protection from everything bad. They are polarities, they are the blend of storm and calm and this difference of them makes them deeply in love with each other and they can't live without each other.
She is his air and his storm to take him away from all those duties and he is a shelter where she can hide when she is too tired of being wild and where she can restore her strength fro further bringing happiness and joy for him.
