Lurky Menaces and Bamboo Plant Thingys

While going through my nightly routine I suddenly hear a strange and ominous noise.  Of course I'm locked in the bathroom and my phone is elsewhere.  Armed with a can of air freshener and a comb (pointy end out) I decide to check it out. Leaving the bathroom I notice the front door is slightly ajar. After soiling myself I think that it must be because my roommate left in such a rush to get to work that she didnt fully close the door. 

That's the logical side.  However I still decide to check out the 4 places that some menace could be hiding.  Thankfully there was no one lurking in the closets or behind the small bamboo plant thing. 

This left the balcony. 

Suddenly I had a flash of any horror movie I've seen where the damsel (that's me) checks out the menacing noise and is promptly dismembered. This is when I decided to close and lock the balcony door (on the 24th floor) in order to show the murderer/cannibal menace who the boss is. Then promptly turned on all the lights and ran back to the security of my bedroom. 

So far. No menace. 

Lesson learned?  I have a slightly over active imagination. 

I hope the lurky menace doesn't have an axe... Or know how to pick a flimsy lock.
