[Verse 1]
Congratulations, you played me, made me your perfect fool
I thought that you would be a lot more mature, it's not true
Oh, this is funny for you right now but just wait a bit
One day I promise you'll see it won't be me suffering
You let me burn, you let me bleed, you let me hurt to death
You wouldn't care if in front of you I took my last breath
One day your heart and your soul will be boiling with regret
From your manipulative ways and your infantile threats

[Pre-Chorus]
But no, you never thought I'd let you go
Oh no, you thought that I would always need you
Well, it's hard
When you're the one that's gasping for air
I don't need you there

[Chorus]
Knock, knock, knock, knock on my door
You can knock some more
I'll keep knocking right along with you
To the sound that our heartbeats used to do
Snap my fingers and you'll snap yours
Then we'll stomp the floor
Sing along to our melody
Even if we're a tiny little bit off key
I'm sorry it had to be this way
But I'll enjoy it when you walk away
(Come on!)
[Verse 2]
You never treated me like you promised you always would
Made up excuses that no human ever really should
One day your heart and your soul will be boiling with defeat
'Cause I'll be ruling up on top and you'll look up at me

[Pre-Chorus]
But no, you never thought I'd let you go
Oh no, you thought that I would always need you
Well, it's hard
When you're the one that's gasping for air
I don't need you there

[Chorus]
Knock, knock, knock, knock on my door
You can knock some more
I'll keep knocking right along with you
To the sound that our heartbeats used to do
Snap my fingers and you'll snap yours
Then we'll stomp the floor
Sing along to our melody
Even if we're a tiny little bit off key
I'm sorry it had to be this way
But I'll enjoy it when you walk away

[Bridge]
And you keep knocking at my door
And I don't even know what for
I've said it a million times
And I've already left you...
Behind
Oh, oh, say!

[Chorus]
Knock, knock, knock, knock on my door
You can knock some more
I'll keep knocking right along with you
To the sound that our heartbeats used to do
Snap my fingers and you'll snap yours
Then we'll stomp the floor
Sing along to our melody
Even if we're a tiny little bit off key
I'm sorry it had to be this way
