We all, at one time or another , were like a rock star, singing and dancing along to our favourite song. Most of us have done this in our own room when we were kids or even when we grew up. Me? I love to do that when I drive! I turn on the radio, find a song that I can sing along, and soon my arms are in the air. I am moving along to the music. Most of the time, I do this on my way to work.

Yes, that is true. I will be in my nice work clothes in my car. Someone may look at me strangely or even laugh at me when I stopped at a traffic light. Personally I love to get lost in the music. That can lead me to share with you the importance of being silly!

The meaning of the word silly, according to the dictionary is : stupid, foolish and nonsensical. I know many people do not want to look foolish. So they are always serious in their life, but in fact that is really stupid.

No one is perfect, I repeat: no one is perfect. I don’t care how educated, how thin, how beautiful, how simple, how frugal(朴素的), how rich, and so on … No one is perfect! So why pretend(假装) to be something you are not?  

Life is so short…_________, so why waste a single second on being so “perfect”?

When we were kids, we had no idea of fear and we had no care in the world so we could do things without worrying about how we appeared to others. However, as we grew up, we lost that kind of feeling.

So don’t be afraid to be silly. The next time you feel down, go and turn on your favourite song , sing and dance along just like there is no tomorrow. Or watch something that makes you laugh. Trust me, you will feel a whole lot better, and who doesn’t want to feel good.
