How Do You Know?

It started off great
At 7 or 8 then we talked all night
So late that you got in my head
Can't believe what you said
It's so crazy, it's so true

You said I can't believe yourself
If no one else was there
And how can you know what's true
If nobody else cares?

Like how do you know?
When a feeling changes
How do you know it?
When that feeling is gone
How do you know so true the things that you do
How do you know me?
Know me at all?
How do you know me?
Know me at all?

When it got to be 4, you opened the door
Just to hear that music a little bit more
For the very first time you opened my eyes
It's so strange
It's so right
You said:

Don't cry, the water's fine
As long as you can swim
But you can't know what it's like
If you never jump in

How do you know?
When a feeling changes
How do you know it?
When that feeling is gone
How do you know so true the things that you do
How do you know me?
Know me at all?
How do you know it?

You know this time keeps ticking around me
I feel like I could tell you something again?

But then

How do you know?
When a feeling changes
How do you know it?
When that feeling is gone
How do you know so true the things that you do
Like how do you know me?
Know me at all?

And how do you know?
When a feeling changes
How do you know it?
When that feeling is gone
How do you know so true the things that you do
Like how do you know me?
Know me at all?
