These days I found it more and more difficult to distinguish men from women. After a singer became famous for his role acting as a woman, many men began to follow suit devotedly. Some men are inclined to be dressed up like women. They also like to stay at home doing housework and attending on their wives patiently. In the meantime, there are quite a few manly females around us. They are short-haired and wear, drink and smoke as men. Some of them are more capable than the men of average ability. These tendencies would be likely to cause people's confusion in distinguishing between males and females.
