Always treat people how you want to be treated and if they can’t respect you, then it’s time for us to leave the negative in the past and let them go (family, friends etc ) ~ Herrera Heather
However, it is always better to stay true to yourself no matter what. Even when you do notice that you treat others better than they treat you. Life is Good! ~ Shirley Mitchell
People will notice the change in your attitude 
A gentle tone can change the direction of a conversation 
If you’re going to leave, then do it today 
Give a portion of your life to someone
