[Verse 1: Lupe Fiasco]
She said there was no love in her heart
'Cause one day a rapist attacked her and broke that all apart
She said there was no way to fix it or to cover her scars
Then one day a guy came along that probably could help her start
He was sincere, made her believe it was safe for her to trust again

In the economic peckin' order
Emergency relief distribution systems is in disorder
He's checkin' water, makin' sure it's safe enough for his daughter
To float across in the boat he built
Hopefully strong enough to support her
Prayin' border patrols don't catch her ass, process and deport her
Before she reach the shore of the land of the free
Where they feed you, treat you like equals
Deceive you, stamp you and call you illegal, and there's an

[Bridge: Sarah Green]
There's someone here and it's not me
How could this be? I locked my doors (This be)
Kept my armies on my shore (My shore)
And point my rockets at my sky
I'm so fortified
I built my walls so high (So high)
So why, oh why? (So, why?)

Intruder, intruder, intruder (Intruder), intruder
Intruder, intruder (Intruder), intruder, intruder
