Anytime the sun isn't above the horizon
Twilight, after the sun goes down.
I am a night owl, and I like to party all night long.
I'm a morning person. I love the sound of roosters crowing as the sun comes up over the horizon.
It might be a vampire.
Nature is a wonder, they 'see' with sonar
Ah, bird of night
Vampires have no use for email
I amp-up the eyeliner to look scary
Vampire with cape and fangs
Cloaked in darkness
I knock on the door.
Through a door.
I saunter in
I fly in the window
