K is for Kindness
Be kind, for everyone you meet is fighting a hard battle.
The saying is attributed to Plato but almost certainly comes from much later in time ( http://quoteinvestigator.com/2010/06/29/be-kind/ ) Nevertheless, whenever it was coined and whoever coined it doesn’t matter.
The Dalai Lama’s equally pithy quote, Be kind whenever possible. It is always possible https://www.brainyquote.com/quotes/quotes/d/dalailama378036.html takes us further.
Kindness is not mushiness, a sentimental thing, though some see it as weakness. To be kind is to be mindful that everyone is liable to be struggling even when we cannot see the evidence of it.
Random acts of senseless kindness are often ways of being kind to strangers and letting the winds of fate decide where the benefits may fall.
Though one should beware of the temptation to play God in these circumstances, or of taking control of someone else’s life by these acts, or even of the whole thing backfiring because of thoughtlessness and a lack of planning (see the negative effects in the wiki article).
Just.. be kind.
