It isn't all that interesting.
About a month or so ago, I was asleep in bed at around 3-3:30am when I hear my door shut. It is a bit of a heavy door, so if you just let it swing shut without grabbing it and closing it yourself, it is a bit loud. So thought, "WTF?" and roll over in bed. There was a guy standing in my bedroom doorway. His hands were at his side, and I could easily see there was nothing in his hands. He was kind of a small dude and was wearing skinny jeans and a small t-shirt, so I was pretty sure he didn't have any weapons on him and was confident I could literally pick him up and throw him if need be.
I don't remember if I said, "Who the F are you?" or "What the F are you doing here?", but anyway, I got up and said, "You gotta go." and grabbed him by the shoulders and walked him out the door and locked it. Then, I went back to sleep.
Thinking back, I went to Costco that day, so I think I had my hands full when I got home and forgot to lock my door. There was a party that night on the floor that I live on, so I'm guessing the guy was a drunk party goer that got lost and started trying door knobs. The weirdest part is that he didn't say or really do anything the entire time, so I don't really know where he came from. I also have no idea where he went after I closed my door. I haven't seen him since.
Since this is another gun related thread, I guess I should point out that I had a loaded gun on my nightstand that I walked past to show the guy the door. Like I said, he didn't pose any real threat to me. He was just a drunk guy stumbling around and my dumbass left my door unlocked.
