"Prejudices are the chains formed by ignorance to keep men apart."
~ Countess of Blessington ~
Each of us is ever evolving and forever new, and unpredictable, and capable of great wisdom and unexpected insight and kindness and their opposite. It depends on the day, the weather, our mood, and our state of consciousness. Consequently, acceptance of whatever may show up is helpful when dealing with people, and compassion, and the honest appreciation that whatever negative judgment we dole out could just as easily be said about us.
Being human means we're all changeable and ever fresh.
