Answer:
The quote has one simple meaning to me, that you should always be kind no matter the consequences. "When given the choice between right, or being kind, be kind," is just a symbol that kindness is valued above all else. If you were given the choice by a friend who asks how they look in an outfit or if something suits them nicely, and it doesn't. The right thing to do is to be honest and say that it doesn't work for them, but the kind thing to do is to tell them it does. In the end, kindness will win you your friends happiness, while the right thing might hurt them.
