What's In A Woman's Heart

First of all, she said she had fun,
then her face looks so dun.
I'm wandering in my heart,
is this her way to break apart?
but everying has just begun!

So, we had a seamy start,
she sees me as a spare part.
But I can't see the core,
I'm still not sure.
I guess no man can understand what's in a woman's heart.
