...and some scene from the movie!
I will close this post with my favorite lines from the Beethoven third letter
"...my thoughts go out to you, my Immortal Beloved- I can live only wholly with you or not at all -Be calm, only by a calm consideration of our existence can we achieve our purpose to live together - Be calm - love me - today - yesterday - what tearful longings for you - you - you - my life - my all - farewell. Oh continue to love me - never misjudge the most faithful heart of your beloved.
(Ludwig Van Beethoven)
