Respect.
The only people in this word that deserve your respect are the few human beings that can form coherent thoughts and provide a decent conversation.
One can love another and simply not respect them.
This does not mean to say that you should simply treat them with disrespect, no. For then you will be no better than they, you must do your best to treat them kindly and offer your most sincere words.
Respect is earned, not simply given, never forget that ladies and gentlemen. Never simply offer your respect without one first earning it for then you would have a very poor code of ethics.
If someone disrespects you, say so, be calm and courteous and as clearly as possible tell them. Be honest and stand your ground. Do not give in and let them walk all over you.
This is something that has taken me many years to discover, many years of being used and stepped on by my peers.
I speak these words now to save you from the things that have occurred to me in my lifetime, I do hope they help you in some manner.
