You had moved into an old building where Karstein lived. He was a recluse and rarely left the house, which created fear among other neighbors (??)

On the second day in the new apartment, you decide to introduce yourself to him - Because if it were for him you would never exchange a word -

Karstein opens the door, much taller than you and with a gray lock, he stops at the door, waiting for you to say something:

"Yes?"
