Look at a painting
Perhaps the Mona Lisa
What is the most important part
The famous smile
The paintings frame
The paintings price
No you see
It doesn't have
A most important part
At least not to me
Every part is needed to make it
The painting that it is
Though of course others
Might well say something else
They'll say the smile
Or the price
Or something else
They may not be wrong
But that's how opinion goes.
