Nor the worst, but by far the weirdest: I was renting a studio apartment in center city Philadelphia a few years ago. I was on the eighth floor. I could regularly hear mice scrambling through the walls. I had all entry points (or so I thought) plugged up to keep them out of my space. I used a pull out sleeper sofa as my bed and one day, after a particularly long day, I fell asleep hard in the early evening. I lived alone…did I mention that? No pets, no other people. So I wake up to this rustling sound. Without fully lifting my head, I turn and look toward the sound. What I see can only be described as two little brother mice using a plastic grocery bag on the floor as their playground. One sat in the middle of the bag while the other one ran circles around the perimeter of the bad, causing it to puff up. The little guy riding the bag would then jump up and down on the puffy bag. I stared in disbelief for a few moments before saying, “hey…what are you doing!?”…to the mice. Wtf? They ran off and I went back to sleep.
