想问一首英文歌曲的歌名

可能是Avril Lavigne（艾薇尔）的Complicated，里面这段歌词：But you become Somebody else round everyone else. Watching your back,Like you can't relax.You trying to be cool, You look like a fool to me的大意就是看你现在就像个傻子，活得都不像自已。

歌词：
Avril Lavigne - Complicated

Uh Huh Life's like this
Uh Huh Uh Huh
That's the way it is

Cause life's like this
Uh Huh Uh Huh
That's the way it is

Chill out
What you yelling for?
Lay back
It's all been done before
And if you could only let it be
You will see

I like you the way you are
When we're driving in your car
And you're talking to me one-on-one
But you become

Somebody else r
