Upstairs, Paul was still scrubbing the wall with the toilet paper, the disinfectant spray now the stronger scent in the air, despite the olfactory power of Carlie's digestive pyrotechnics.  All the way across the house, on another floor, he couldn't hear the argument downstairs clearly.  But he could hear the raised voices.  Paul stood, and went to the bathroom quickly, washing his hands before he got to the staircase, taking two steps at a time.  Though he was about to turn 40 years old, he was still a fit man, so it wouldn't take him long to reach his daughters' room.
