Everything happens for a reason.
Everything has its cause.
Every city has its borders.
Every place has its laws.
What goes around comes around.
Everything has an effect.
A feather falls but makes no sound.
Where a ball bounces right back.
Theres always a what, when, and why.
A problem to be solved.
A hidden truth in every lie.
An effect to every cause.
