Bbm Gb Ab




Bbm
I'm in love with you girl 'cause you're on my mind
Gb
You're the one I think about most every time
Ab
And when you pack a smile in everything you do
Ab
Don't you understand, girl, this love is true 
Bbm
You're soft, succulent so sweet and thin
Gb
That's kind of like a vision upon your skin
Ab
It lightens up my day, and that's oh so true
Ab
Together we're one separated we're two
Bbm
To make you all mine, all mine is my desire
Gb
'Cause you contain a quality, you that I admire
Ab
You're pretty plain and simple, you rule my world so try to understand
