One night at about 3am my wife was getting up from the toilet to return to bed when she heard a little noise. It was a suspiciously rodent like sound that seemed to be right in the bathroom with her.
She, of course, froze and listened attentively for any further sign of invaders. After a moment, satisfied that she was alone, she took a step for the door. Rodent scratchy sounds again! She froze, not breathing. Silence. Her heart beat fast as she once again tried to retreat from the bathroom.
This time the noise was accompanied by something touching the back of her leg! That was too much to bear. She literally flew the 8 feet to the bed, clearing the foot board by a couple feet, to land screaming by my side.
The culprit was right there in plain sight, a trail of toilet paper neatly marked the path from bed to the bathroom.
