I deliberated for quite some time and decided that a letter is the most appropriate to convey my wishes.
I don't know the origin of Vampires, nor our terminus. 
Yet  I believe in science. Upon science, we built civilization to pass down through generations to embody so many ordinary days with special meaning. It reminds us of who we are, even though we are Vampires now.
My apologies. I'm not good at this... I just wanted to wish you Happy Valentine's Day.
