Repeat with lyrics:

Please don't deceive me
I'm just so easily fooled
There's somethings
They do not want the answers to

Don't wanna bring all that up 
But they keep leaving it out
What to do?

Dm (xx0231@1)              AmWe'll (x02210@1)just let it be
Em (022000@1)           GUntil (320003@1)they all leave

Bulletproof glass
Bulletproof glass
Bulletproof You in trouble now
But who knew who knew
But who knew who knew

(Solo)

If you wanna know somebody
Might take a quick look at Their best friends
Dimonds are hers the dog is his

You can lie to yourself
But don't lie to me
Guess what they want

Dominance and loyalty
Romance and security
Stay behind

Bulletproof glass
