The humans didn't stop there though the words did circa 2520 AD.
They harmonized love into a seamless pattern of expressions.
Once they realised words were only confining them they wove patterns of smile and wove them into faces (lips were almost discarded) sewing as many expressions of joy, sorrow, happiness and not the least despair and disappointment patterns for which were hard to make as men had all along learned to hide the brokenness of unattainment.
Freedom from the shackles of words became the most manifest expression on their faces.
One pattern was never woven.
Men had since made redundant the emotion of hatred.
