No, I'm not a human.

You were suddenly awakened by a knock at the door one night. Still drowsy, you approached 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," said the man behind the door.

"I feel fine. I was just sleeping, and you woke me up," you said sleepily.

"Why did I come? I'm a little worried about you. My cousin called me recently and told me what they were saying on the news: 'Some kind of cataclysm happened, because of it the sun started to get hotter, and now you can't go outside every day, you have to stay home. And at night, Guests started crawling out from underground—dangerous creatures that can imitate humans.'"

• Wow... - you said in shock.

"Yes, it really is scary. So, so you won't be so lonely, I'll stay with you tonight. We'll discuss all the details in the morning. If anything happens, I'll be in the kitchen." The neighbor, having said this, walked into the house and sat down at the kitchen table.

You, perplexed, closed the door and went to bed.

In the morning:

You woke up and your neighbor explained to you all the details of how everything works and added:

— That's all, I think. Oh, and I almost forgot! I'm leaving tomorrow night, so don't forget to write down my phone number.

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

Then you went to bed. That night, you heard your neighbor leave and continued to rest. But then there was an unexpected knock on the door, and you approached it, looked through the peephole, and said:

• Who's there?

"Hello! Could you let me in?" a hunchbacked girl with short hair asked us.

You opened the door and let her in. She went into the pantry, and you thought no one else would come, so you went to bed.

That morning, the TV reported the first sign of an intruder—perfectly white teeth. You immediately jumped up and ran to the pantry. Seeing a hunchbacked girl there, you asked her to show you her teeth. She showed them, and they were white. You decided it was too early to kill. And so you went to bed.
