There are so many things that he doesn't know.
He doesn't know that I lay in bed at night thinking of him.
He doesn't know that he occupies my mind 100% of the time.
He doesn't know that all day every day I'm thinking of ways to make him happy.
He doesn't know that my greatest joy in life is seeing him smile.
He doesn't know that when I wake up in the morning my first thought is of him.
He doesn't know that I would do anything to show how much I love him.
He just simply doesn't know.
