It is a letter so special that it even had a small supporting role in the 'Sex and the City' movie. Carrie is doing research for a new book and reads this exact love letter of Beethoven's to Big as they sit in bed together at night. It becomes the the clincher at the end of the movie as Big attempts to win Carrie back. He sends her multiple love letters via email from the book, 'Love Letters of Great Men,' including this entry. As Carrie and Big tie the knot in city hall during the final moments of the film, he whispers the last lines of Beethoven's letter in her ear:
Ever thine. Ever Mine. Ever ours.
For Beethoven, it is a true outpouring of love and devotion; a proclamation of love from a distance with hopes of one day being together. Until then, she is in his soul, embedded there, and his heart belongs to no one but her. I am forever yours. You are forever mine. Forever it will be us.
