You've got so much confidence
Sometimes I don't know
Some things need time
To reveal the way they grow

Now I'm not saying I doubt you
I've got no reasons to
But now we got a video
The silly things that you do

How can you be so sure
About it?
How can you be so sure
That you won't change your mind?
How can you be so sure
How you feel when you know that you're changing
All the time?

You said we could make it
If we wished upon a star
We'd always be together
No matter where we are
I told you only yesterday
We'd always feel this way
But now you wanna tell me
You're feelin' different today

How can you be so sure
About it?
How can you be so sure
That you won't change your mind?
How can you be so sure
How you feel when you know that you're changing
All the time?
