I think about you each time before I fall asleep. I imagine that you are here with me. Then I hug my pillow tight thinking it is you and fall asleep thinking I am sleeping in the arms of the sweetest person in the world. After this I just wait to fall asleep so that I can dream all night about you. Good night sweetheart.
