Some things are cultural.  Like this command.  In many places in the world, kissing as a greeting is not be a problem.  In some places, it is a huge issue.  The point is the principle–show one another righteous honor.

How do you do that in your culture?  How do we do that in our culture?

Then do it.

Your simple acts of love, respect, honor, and friendship matter.

Your simple acts of disinterest, lack of love, missing welcome, and distance also matter,

Simply act.

Act simply.

And show love.
