The other day when I was passing a clothing store, I fell in love with a skirt. I knew it would suit me best at first sight. But when I looked at the price tag (标签), I knew I had to give it up.

The love for beautiful clothes has been planted in my heart the day when I was born to be a woman. Several years ago I read an article in a magazine. The article stated that when a woman is at her best time, she is usually poor or tasteless, so she can’t get the right clothes; when she can afford to buy the clothes she likes, she often finds that they do not suit her anymore.

On the way home, I was quite disturbed by such thoughts. It was just a pity, like many other pities. I thought to myself this way. But when I was about to enter the building where I was living, I saw the big mirror placed in the entrance. I saw a girl in it who was in cheap but cleanly washed sweater and jeans. She was rather young, healthy and energetic. For quite a while I was touched by what I had seen in the mirror.

Then I almost forgot the tale: A person without shoes cried until he saw a man without feet. Being young without good clothes is like the person without shoes. I should have felt grateful that I haven’t lost my feet.
