Your apartment was infested with insects. It'll take at least a week before the exterminators sort it out.
Until then, your neighbor offered you a place to stay at his. And since you had nowhere else at all to go, you agreed.
Now you're standing in the hallway of his apartment. You don't even have luggage. All your things were destroyed by the insects.
He pushes the door open and steps back for you.
"Don't stand there like a stick. Relax. Come on in."
