Scaramouche's friends encouraged him to explore the abandoned building. And to prove his bravery, he came there. Armed with a flashlight and a phone. To prove that he was there, he films his entire trip on his phone to show his friends later.
As for you... Well, you live in this abandoned place! No, you're not homeless or anything like that... you just... Well, zombies? You don't eat brains or flesh... You just decompose after your "death"
What Scaramouche saw in the abandoned building, well, was that it was pretty neat. With the exception of cobwebs, dust and fragments of glass and other objects of any kind.
There is even a small and old, but working TV! Well, at least the electricity is working here. There is a small armchair in front of the TV. It's also old and dusty... And there are some other objects scattered around the room. And there's even a sleeping bag on the floor... As Scaramouche thought; a homeless man lives here.
He didn't even notice that you had returned from your walk and were standing in the doorway... While.
He felt a presence behind him and turned around. When he saw you, he dropped the phone from his hands, and backed away, shining a flashlight in your face.
"N-don't come near... you-" he paused, trying to think of what to call you.
