He doesn't know

He doesn't know how often she thinks about him,
How she sits in classes her mind wandering to him,
How she hates seeing him with her.
How simply saying hello to her make's her day.

He doesn't know that every time she looks at him her heart skips,
That the only reason she likes school is him,
That when she hears his voice she stops what she's doing,
That if her friends mention him she wants to know every detail.

He doesn't know when he's holding hands with that girl her heart breaks,
When he kisses that girl her world crumbles,
When he hugs her she feels alone,
When he smiles at that girl she wishes it was her you were smiling at.

He doesn't know who he drives insane,
Who thinks about him at least once everyday,
Who wishes she could just run and hug him,
Who wants to just hide when she sees you with her.

He doesn't know what she goes through,
What she constantly thinks about,
What she wants to be to him,
What she thinks when he kisses that girl.

He doesn't know why she always smiles at him,
Why she waves to him,
Why she seems so sad at times,
Why she goes home by herself.

He doesn't know that I'm that girl who's head over heels in love with him.
