Where I am from, you don’t do a half-ass job. You always give it all you got.
If my asshole coach were forcing me to compete in a discipline for which I was demonstrably unsuited, and if - to boot! - I were suffering medical problems as a result of that, I (as a Texan) would most certainly either refuse entirely (most honorable and consistent choice) or at least run at a speed which would not endanger my health.
QUESTION: How would you have reacted if it hadn't been you, but rather your little brother whom the coach had been abusing in this fashion?
Regards,
