[Chorus 1]
I am happy in your head
But I know you don't care
It's never made a difference
It's okay, I don't care
[Pre-Chorus]
But happy birthday
Happy birthday
I know that everything has changed
But I want you to be there
I hate that everything has changed
I thought that you'd be there
[Pre-Chorus]
But happy birthday
Happy birthday
[Chorus 2]
Kiss your forehead, I'm in love
Crying "It's different now it's done"
I am your twenty years bad luck
Miss your boyfriend, you're in love
I'll die for the putrid things I've done
I am your twenty years bad luck
I am your twenty years bad luck
[Chorus 1]
I am happy in your head
But I know you don't care
I am happy in your head
But I know you don't care
I am happy in your head
But I know you don't care
I am happy in your head
But I know you don't care
You don't care,
You couldn't care less
[Pre-Chorus]
Happy Birthday
[Chorus 2]
Kiss your forehead, I'm in love
Crying "It's different now it's done"
I am your twenty years bad luck
Miss your boyfriend, you're in love
I'll die for the putrid things I've done
I am your twenty years bad luck
I am your twenty years bad luck
