So I recently moved, and I live alone. 

I was in my room and somebody knocked on the door. I didn’t order any packages or food, nor was anyone coming over. I didn’t put in a maintenance request, and if it was an emergency they have a key to enter anyways. Plus, not all of my friends even know where I live right now since I just moved and haven’t invited many of them over yet due to being busy. 

So they knocked a few times. Then I heard them go out to the front porch, and they rang my doorbell. Then they came back and knocked even more than they did the first time.

Maybe I should’ve answered it, but I was paralyzed. I couldn’t even look out of the peephole because I was scared they’d hear me behind the door. 

I don’t know what that was. 20 minutes after, I opened my door and there was no note (management leaves notes on our doors about scheduled maintenance, notices, etc.) and no item around my door. 

I also heard them leave the building after I failed to answer their last knock, so I don’t think they had the wrong door because I would’ve heard them go up the stairs or knock on my neighbr’s door. 

So yeah. I don’t know what that was. Management/landlord would’ve left a note or called me, most of my friends don’t even have my updated address, my family would’ve just called me.... 

I also took some clothes out to dry earlier, and I noticed the back gate was ajar. I went inside and someone knocked maybe 30 minutes later, and when I was peeping out various windows I noticed the back gate was closed. Aghh!
