Traditionally, women are the ones who would cook.
Having a man cooking better than a woman would compel the woman to try to cook better than the man.
Sometimes, in a relationship, a man who can cook while a woman who can't cook appears 'uneasy' or 'weird' for the woman.
Thus, man is an enemy.
A man is a friend because even if the woman can't cook, having a man who can is a blessing.
Another reason is in some cases when the woman is sick or unable to make the meal, the man can step in to help and to cook instead.
This concludes the twist of how a man can be an enemy and a friend to all women.
The End.
