You can't pay attention in class because you are too busy writing your first name with his last.
When all you can do to stop thinking of him is to sleep but even then he is in your dreams
When you call him and talk to him hours on end
When you are being chased by him, when he is trying to hug you, and you pretend you don't like it but you don't put up a fight and you think "Never ever let go!"
Is when you think about your future together and he thinks the same way.
When he promises you two will be together when you are sixteen
