Who Knows(谁知道) Music：Avril Lavigne/Chantal Kreviazuk
Why do you look so familiar I could swear that I have seen your face before I think I like that you seem sincere I think I'd like to get to know you a little bit more
Chorus I think there's something more Life's worth living for
Who knows what could happen Do what you do Just keep on laughing One thing's true There's always a brand new day I'm gonna live today like it's my last day
How do you always have an opinion And how do you always find the best way to compromise We don't need to have a reason
We don't need anything we're just wasting time
Chorus (2x) Find yourself 'Cause I can't find you Be yourself Who are you? Find yourself 'Cause I can't find you Be yourself Who are you?
Chorus So you can make it happen Do you best Just keep on laughing I'm telling you There's always a brand new day
