"understand"

How much do we understand others?
How much...?

English word understand is made up of "under" and "stand".

Do you understand others, standing under them?
And, do I?

It's painful not to be understood by others.
The opposite is also said.
It's really regrettable not to understand others.

I want my family to be happy.
I want to understand my family.
And I want them to recover from broken hearts.
