The Lady's Improving

The lady’s improving
So don’t give up hope
You’ll ask, «Is she perfect?»
My answer is nope!
I know what you’re doing
Her range needs expanding
Her edges need sanding
But she can become a sure bet!
So I’m begging you sir
Don’t give up on her yet
You’re trying to appeal to the fan in me
Well, it won’t work
I’m not a fan anymore
The lady’s improving
So much that she gloats
I know you’ve got standards
Feel free to give notes
