Last night I washed my face and got ready for bed, and as I walked across the hall to my room, I saw a big dark blob skittering along the floor. In my bare feet, and without contacts in, I groped around for a shoe or something to squash it with. When I turned back around - with heavy book in hand - I was just in time to see the thing dart into my bedroom and go behind the door.
When I followed in hot pursuit, behind the door was empty.
I had lost a big dark crawly hoppy thing in my bedroom.
Try as I might, I could not find it, even after I retrieved my wits and my glasses.
It was a long night trying to get to sleep. I still can't decide whether it was a mouse or a cockroach.
