I come home late to my apartment...just fed on some poor guy, he had it coming trying to steal my purse. I had a bit of blood on my face, no worries. I'll just clean it...I turn to the kitchen...to see my roommate with her face stuffed with pizza from last night...oh shit. She looks anxious...the blood!? Shit I forgot!?

"Oh...uhm...it's ketchup?"
