Leave a trail of chocolate kisses from the enterance of her home to her bedroom and onto the bed. Leave a rose and a note asking "Now that I've kissed the ground you walk on, will you marry me?" Or, in the case of a friend that you want to become romantic with, "will you go out with me?" You might use this idea in other situations where you don't have access to their home... at an office, at a family home with the cooperation of relatives, in a classroom, etc. You might also send an existing partner a romantic reminder that you daily "kiss the ground they walk on."
