A true core does not shake

Everyone claims to be the core,
but a real core doesn't mock.
They don't just avoid mocking; they don't even use sarcastic words.
They silently endure and provide support.
Those who talk big with words lighter than a feather are not the core.
Cores do not cause conflict.
It is the same in sports as it is in professional life.
If the cores shake, everything collapses.
Cores don't have the luxury of talking nonsense,
because they must always maintain the center.
Do you understand what I mean?
Those who call themselves "cores" talk way too much.
A real core doesn't let their words fly so lightly.
Instead, they support you regardless.
Those who just talk big are not the core.
