If you had asked me, I'd have told you
There ain't nothin' I don't know
Like no matter how I hurt her, I just knew she'd never go
Up until the day she left me, I'd have sworn I'd never crawl
Well it's amazing just how much I've learned
Since I thought I knew it all.

Figured she'd be much too frightened, to make it on her own
So I was sure that she'd come cryin'
After just one night alone
I kept waitin' by the telephone, so certain she would call
It's amazing just how much I've learned
Since I thought I knew it all.

I never knew a broken heart
Could turn you inside out
I didn't know, that I didn't know
What love was all about.

If she came walking through the front door
There's a million things I say
Like "I love you" and "I missed you, please don't ever go away."
And if you would just forgive me
I'll be at your beck and call
'Cause it's amazing just how much I've learned
Since I thought I knew it all.

It's amazing just how much I've learned
Since I thought I knew it all...
