A day without you is like a broken pencil.
You are interested in learning what to text a girl to make her smile.
I know you like music, so I was wondering if you would go to a concert with me.
— You are the whole world for me.
This sounds like something straight out of a movie and the girl in question is sure to feel like a movie star when you tell her that you love her in this way.
You are the only thing in my mind.
