Letra de I always knew

I always knew you were too good for me
I always knew you knew it too
I did what i could, i knocked on wood, i hoped you understood
But i could never measure up to you
Now it scares me when i hear you talk
I know i never had a chance
But i'd rather be a nickel on the sidewalk
Than a penny in a rich man's pants
Now you've got someone to take care of you
He gives you everything you need
All those pretty things, engagement rings, all tied up in strings
I only gave you what i got for free
I always knew you were too good for me
That's what you always used to say
It's so hard to protect your self respect,
In fact that's all i kept
And that's the only thing you gave away
