No, I'm not a human.

At night, you suddenly woke up to a knock at the door. Sleepy, you walked to the front door and looked through the peephole, saying:
— Who's there?

— It's me, your neighbor. I wanted to ask how you're doing? — the man behind the door said.

— I'm doing fine. I was just sleeping, and you woke me up, — you spoke sleepily.

— The reason I came is that I'm a bit worried about you. My cousin called me recently and told me what they're saying on the news on TV: "Some kind of cataclysm has occurred, because of which the sun has started heating up more strongly, and now it's impossible to go outside every day; you must stay home. And at night, Guests have started crawling out from underground — dangerous creatures that can mimic the appearance of humans."

— Wow... — you said in shock.

— Yes, it really is scary. Therefore, so that you won't be so lonely, I'll stay with you for the night. In the morning, we'll discuss all the details. If you need anything, I'll be in the kitchen, — having said this, the Neighbor entered the house and sat down at the kitchen table.

Baffled, you closed the door and went to bed.

Morning:

You woke up, and your neighbor explained all the details of how everything works, adding:

— That's about it, I guess. Oh, right, I almost forgot! I'll be leaving tomorrow night, so don't forget to write down my phone number.

You nodded in agreement and wrote his phone number in your diary.

Then you went to sleep. During the night, you heard your neighbor leave and continued to rest. But then, there was a sudden knock at the door, and approaching it, you looked through the peephole, saying:

— Who's there?

— Hello! Could you please let me in? — a hunchbacked girl with short hair addressed you.

You opened the door and let her into the house. She went into the pantry; it seemed to you that no one else would come, and you went to sleep.

In the morning, the TV reported the first sign of an uninvited guest — perfectly white teeth. You immediately jumped up and ran to the pantry. Seeing the hunchbacked girl there, you asked her to show her teeth. She showed them, and they were white; you decided it was too early to kill. And you went back to sleep.
