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.
