What I Don't Know

I love girls in pictures, I love 'em in song
 I've known me a few before she came along
 This one tested my metal, yeah, she grounded down good
 Turns out what I don't know about women fills a mighty big book
 She came without warning, she knocked down the screen
 Said, what I'm gonna show you somethin' you never seen
 Well, what was I thinkin' when I gave her a key
 What I don't know about women might be the end of me
 What I don't know about women, I guess I don't know too much
 Some roses at the beginning, well, it used to be enough
 What I don't know about women fills a might big book
 The darkest cloud ever was over my house
 And it felt like forever soon love had run out
 She left like she came in so I took one last look
 Turns out what I don't know about women
 What I don't know about women
 What I don't know about women fills a mighty big book
