Input: Text: it was about 10pm last night, and we received a knock on our door, and then the doorbell rang. for context, my roommate and i are both females. neither of us were expecting anyone, especially so late, so we freaked out a bit.
we looked out the peep hole in our door and didn't see anyone, and didn't want to open it in case there was someone waiting outside around the corner. we bolted our door lock.

about an hour later, we receive two more knocks and the bell rings twice more.
i'm fully freaked out at this point. i check the lock again and lock my door to my room. i'm planning to call the cops if it happens again and planning on sleeping with the lights on so, if the person is watching from outside, they think i'm awake (don't know why that would help anyway). enter sandman is playing in my head as i'm fighting to stay awake. i had somewhere to be at 9am, and at 1:30am i was still wired. 

i set an alarm early to wake up and get some things done before leaving for the day. i slept through it because i was so tired, and ended up waking up at 9:30. but, hey, no one broke in overnight.

my roommate tells me she too the trash out and the figured out why we were receiving these random knocks and doorbell rings: my keys were left in the door lock. overnight. these were our kind neighbors trying to inform us of this. we were so afraid of some creep or criminal, yet they had literally the only tool they needed to break in right in the door.
