Frank, a mortal, thinks heavily on an emotional commitment to his girlfriend Nessa, a vampire.
"After
leaving her apartment, I was outside walking toward Central Park within
five minutes. If I took too long to decide, our relationship would end.
Nessa had been lonely for over four hundred years. She made a choice
about me, perhaps impulsively, but now I knew how much I meant to her.
She would be devastated if I rejected her, and I had no wish to be the
cause of such pain. But I also needed to consider the risks involved.
I
walked along the outside of the park until I found myself in front of
the Museum of Natural History. For all the information it contained, it
didn't have displays about creatures the visitors were better off not
knowing. Nessa, werewolves, and demons didn't exist in any of the
museum's catalogs. However, she was also a woman, one that aroused the
strongest feelings I had ever experienced. Should I make a commitment
based mostly on feelings? I was always so rational. To go with her was
to step into the unknown and far beyond my comfort zone.
When
I looked at my watch, I saw five hours remained until dawn. For once in
my life I decided to go where my heart led. I walked south until I
hailed a cab, and in a few minutes I was back at her apartment. The
strong need I felt to be with her contrasted with how I felt two hours
ago. Time is not measured in minutes or hours but by the manner in which
we experience our lives. When I stood in front of her door, I knew my
decision."
