Man and Woman
Here is a man and he came from Mars and he is strong and stern. He is not able to express his emotions and feeling the way that would let all people know about the pain inside of his soul. A man is strong and he knows he has to be strong because there are people he has to protect and there are people he has to care about, he is a man and he knows what it means.
And here is a woman, she is tender and vulnerable and she is never embarrassed with expressing her emotions and feelings. In case she is hurt she cries and this is the ways he expresses her pain and she never keeps it for herself only. She is not that strong as man and she doesn't have to be that strong because she is a woman and she is tender and vulnerable.
But indeed, they are of the same strength and of the same vulnerability. Though, a man knows it is better for him to keep his feelings for himself because he has to be strong, and woman can express her feelings and reveal her weaknesses because she knows that there is a man who can protect her. They are different and they are polarities and they need each other.
They need each other like two sides of earth need one another. Two sides of earth is the whole Earth and one side is nothing and there will be no life on that hale, that is why the second half is needed and the blend of those is the beauty of this world.
