My version(视力) is getting worse. I can’t even see what is five feet away from me without glasses. ①我拒绝戴眼镜,though I know I need to. I’m afraid they will make me look ugly. Besides, I can do well without them. These were my thoughts two years ago, when I was in the sixth grade. An embarrassing experience taught me that what I was thinking was wrong.

School has been out for two months. I was going to junior high school soon, where I was sure that looks are everything. So the question still remained there. Should I, Or should I not, wear glasses? The question was still in my mind when my family and I attended a wedding(婚礼) late in the summer.

During the wedding, I drank too much juice. Soon after it ended, I walked quickly to the bathroom. Since it was an emergency(紧急) and I couldn’t clearly see which door was ③marked boys. I just opened the nearest door and entered the restroom.

Unluckily, I had entered the wrong restroom. But I didn’t know this until I heard a scream(尖叫声) coming from the entrance when I was washing my hands .

After that, I decided to wear the ugly-looking glasses. I didn’t really ④care about what people thought of me any more, because I never wanted to enter the wrong bathroom again.

On the first day of seventh grade, ⑤my friends didnt make fun of me. Instead they gave me compliments. They thought the glasses made me look more cute and more natural.

So if you know something is right, just do it. ⑥It doesnt matter what others think of you. All that matters is what you think of yourself—and that you can see where you are going!
