Jennifer stuck her tongue out at David. "You can tell me to go back, but I'm not your maid! Bye! I'm not in the mood to study today; you can swim by yourself!" She had come in barefoot and was careful not to walk too fast, afraid of slipping and falling again; her injury had only just healed, and she couldn't afford to hurt herself again. This was what she called an enhanced sense of self-preservation.
David was so furious with Jennifer that he felt like he could explode, but he was also captivated by her cheeky gesture. Without thinking, he charged after her. If he didn't catch this woman today and throw her into the water, he wouldn't be called David.
However, tragedy struck. With water all over the floor and running at full speed, even the most skilled person could slip and fall hard. David hit the back of his head on the ground with a thud that even Jennifer could hear.
