Kindness is not nice.

Nice is soft and inoffensive.
Nice is easy and effects no change, it's cotton wool - not stuffed tight, but just resting on the surface ready to be blown away or trodden into a muddy disinterest. Nice is a damp whisper, a mouse cowering in the corner, taking up as little space as possible, lest it be noticed, lest it presume too much and cause a whisker of offence.

Kindness isn't like that -

Kindness pushes in, claws out, quick and heavy, uninvited, unexpected, taking pleasure in disturbance, in leaving nothing unsaid and little undone in its pursuit of creating a disruption of difference. Kindness counts everyone a target, anybody a likely candidate for a three act matinee and evening performance of loud Kindness. Surprise is its currency, smiles its language, common humankindness its passport to lands yet to be explored, to vast red territories with drumbeats of gratefulness for the opportunity to march in with regiments of compassion and to leave a signature devastation of brutal Kindness.

Kindness is not 'nice'.
Kindness is loving awe-ful.
