Fake My Own Death

"I can be selfish and greedy
But you call it "needy"
You're so defensive, and it ends with
A fight
But there's been a lack of attention
That I dare not mention
Baby, would you even notice if I died? (Died)
Well, what if I fake my own death?
Yeah, I know it's risky, but would that make you miss me?
I'll fake my last breath
You'll regret what you said if you think I'm dead
I'd leave a crime scene behind and I'd run
'Cause that's the only way you'll believe I was gone
What if I fake my own death?
D-d-d-death, fake my own death
D-d-d-death, death, death
D-d-d-death, fake my own death
D-d-d-death, death
Maybe I'm foolish
For wanting someone I could rule with
But that's why when you show no passion at all
I'm irrational, so it's not my fault
You'll say, "She's dramatic, she's pretending"
'Cause only you know how I fake the ending
Tell me, baby, would you notice if I died? (Died)"
