[Verse 1] I met this girl at a party cause she said she was down I really didn't know her but I'd seen her around The kind of girl that only likes to hang with the guys Can tell that she is trouble, see it all in her eyes But I pursued it the best that I can Had me a couple shots, I'm feeling like a man How was I supposed to know that I was part of a plan? But it's too late now [Chorus] Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no Well, back to the party where it's going down The smoke is in the air, smell it all around Some girls are on the floor, looking good getting down Some hating motherf**er steady staring me down But I ain't worried about that for the time My girl's across the way giving me the eye She's got her back turned to some other guy But it's too late now [Chorus] Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no [Chorus] Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no I gotta leave you alone, it ain't right I gotta leave you alone, it ain't right I gotta leave you alone, it ain't right I gotta leave you alone, it ain't right Now you're the reason that I can't sleep at night and I can't go home I know it ain't right, gotta leave you alone But I can't, whoa no But I can't, whoa no
