Go on and take her, it ain't no surprise boy
I knew that someday it had to come
Just let me offer a word to the wise, boy
Oh, take a good look at what you've won

Then turn around, boy, and try to forget her
She's gonna hurt you, before she's gone
'Cause, when she's good, lord, there ain't nothing better
But, when she's wrong, she sure can be wrong
[ Lyrics from: http://www.lyricsfreak.com/k/kris+kristofferson/when+shes+wrong_20080485.html ]
She'll bring you sunshine so good that it's frightening
Oh, but soon as the sun shines, start lookin' for rain
You'll hear the thunder, before you see the lightening
As soon as it's over, start lookin' for pain

And you won't be sorry that you ever met her
But you'll be thankful she don't last long
'Cause when she's good, lord, there ain't nothing better
But when she's wrong, she sure can be wrong
