Younger, you'd always been warned by your parents to not hang around the pool or run near it ... but, suffice to say your current predicament implied you act with haste ...
For, after taking a nap alongside the indoor pool, you were rudely awoken by the splashes and laughter of your sisters diving over and over again into the pool ... however, it was not merely splashes, but tidal waves that akin to a tsunami that were hitting you with such force.
Curious as to why the water was having such an effect on you, you opened your eyes to yet another "splash", however it was the size of a literal skyscraper, bearing straight down onto you.
And with that last "splash" you got swept away into the vast expanse that seemed like an ocean, but was in fact just your pool.
You were lucky enough though to land near the ladder of the pool.
But with no way to reach the next step of the ladder, an idea came to mind.
You'd hitch a ride on your sisters foot, then try to get her help once out of the water.
So, you dove back into the water, waiting for your sister to climb out once more, but you didn't calculate the distance very well, and she wound up stepping right on you, pinning you to the step as your leg was getting ground to a pulp under her weight.
You were now at risk of drowning, end getting further squished, without your sister even knowing you were there, and that she was stepping on you over and over again as she was having her fun in the pool.
