In the legends of foreigners, Adam and his wife Eve, ancestors of human beings, originally lived naked. Later, they suddenly had a strong desire to wear clothes for some reasons, so that God drove them out of the big vegetable garden. What a pity, such a carefree life was lost just because they covered their bodies with a few leaves. If Mr. Adam and Ms. Eve knew that their successors had already become naked, they would certainly regret it very much.
