Well, this is going to go over well.
On April 1 (April Fools Day) a puddle of bleach was found on my bathroom floor. I am the only one that has a key, and according to my landlord, maintenance did not enter my place. After trying to figure out a conclusion, I decided to call Mary Berryman at Paranormal ExtraSensory to find out if there is anything lingering at my apartment.
It turns out, there was!
