Okay, this is a hilarious story, so let me set it up properly.
I live in a relatively quiet building. There are only around 8 apartments, filled with single people and couples all under 40. Everyone keeps to themselves, so it's rare I really say anything to anyone beyond "hello."
My neighbors across the hall are even more extreme. There have been times when this twenty-something couple deliberately walks faster or averts their gaze to avoid even basic pleasantries like "Hello."
So imagine my surprise when, Saturday night, around midnight, I'm in my bed reading when I hear snoring. Really loud snoring. It sounds like it's coming from inside my apartment.
Did new neighbors move in, and this is what I have in store for me, I wonder. I get up and put my ear to the wall. No, it's not coming from there...but it's ...so...loud.
I go into my bathroom, with thoughts that maybe some wild homeless man broke in and is sleeping in my bathtub. You never know. No. No one in the kitchen either. Why is it, then, that while I stand near my front door. Oh. My. God. No way.
I look out my peep-hole and sprawled in front of my door is my neighbor from across the way. Snoring like a mo-fo. In shock, I open the door and try to wake him up. "Dude," I whisper, shaking him, "wake up! You don't want to sleep here." But apparently he does. Whoa. He's out. So I did what any normal person would do: I took a picture! Haha.
At one point (looking through the peep-hole, of course) I see his girlfriend come home. She turns around, sees him on the ground, looks at him for a long time...and goes back into her apartment. WTF?!
The next morning, he was gone. Thank God! But he left his keys. (How'd he get back in? So many questions...so few answers.)
So I put his keys downstairs with a note that said, "Someone had an interesting night." With a smiley face. Geez, louise, his alcohol shame must've been intense...
Giggle
He asked me what he should do. I looked at the passed out guy and saw
that he was lying on his stomach so if he threw up he wouldnt choke on it. Then I asked if he was breathing. Yes. I said to just leave him there and I went back to bed 
Yikes. At least he wasn't in your bathtub.
