<human>: Provide a brief overview of the text.

I live in NYC, in an apartment building on the first floor. 

I was asleep in bed tonight when our door buzzer went off at 4am, waking me up. None of my other three room mates woke since they are heavy sleepers. I thought nothing of it and went back to sleep.

Twice more the buzzer rang, longer this time. In a groggy state I got up and went to the front door. I tried to see the guy buzzing through the peephole, but couldn't make him out.

Then, like the idiot who dies first in a horror film, I left my apartment to go talk to this guy behind the apartment door. He was in his twenties and looked drunk at best.

I asked him if he lived in the building and he said "yeah, let me in." I asked what apartment, and he said 23. When I asked him why they weren't letting him in, he said he didn't know. I asked him why he was calling my apartment, and he didn't answer. I asked him to please stop ringing our apartment and turned to leave. He asked through the glass if i was going to let him in. I told him "no, just call the people in apartment 23," and went back to bed.

Now i can't stop thinking maybe this guy was just a drunk guy who lives in the building, and that I was an absolute inhumane asshole to appear, walk all the way to the door, and then go "nope!" That, or I got a look at a crazy theif/killer/rapist who now knows exactly which apartment I live in.

Would love to hear your take on this, reddit!
<bot>: Guy kept buzzing my apartment at 4am, and I went outside to tell him I wasn't going to let him inside the building. Am I the asshole or is he?
