[Verse 1]

It started out great at seven or eight

Then we talked all night, so late

Then you got in my head, can't believe what you said

It's so crazy, it's so true

[Pre-Chorus]

You said, "You can't believe yourself

If no one else was there

And how can you know what's true

If nobody else cares?" Hmm

[Chorus]

Like how do you know

When a feeling changes?

How do you know it

When the feeling is gone?

How do you know so true

The things that you do?

How do you know me

Know me at all?

[Post-Chorus]

Like how do you know me?

Da-da-da-da-da-da

[Verse 2]

When it got to be four, 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

[Pre-Chorus]

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"

[Chorus]

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? Ah

[Post-Chorus]

How do you know it?

[Bridge]

And all 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 the feeling is gone?

How do you know so true

The things that you do?

Like how do you know me

Know me at all?

[Chorus]

And how do you know

When a feeling changes?

How do you know it

When that feeling is gone?

And how do you know so true

The things that you do?

Like how do you know me

Know me at all? Ah
