By what metric could we attempt to capture the transient ephemerality of joy?
In laughs, smiles and winks?
Feats of silliness and childlike play do not lend themselves well to the finitude of accounting.
The principles of joy follow a different set of rules, or perhaps none at all:
There are no balances.
All loans are interest free, worry free, and carefree.
All loans are automagically approved without review or restriction.
All loans are gifts without expectation of reciprocity.
All gifts of joy paradoxically increase the principal commensurate with the given sum, akin to how a candle's flame that ignites another is not only entirely undiminished but multiplied in full.
Any sum generated is momentary but appreciates and depreciates exponentially in equal measure.
All joy is non-refundable, but definitely transferable and transitively cumulative.
Joy's rate of appreciation increases exponentially as a function of the product of personal enjoyment and individuals involved in any given happenstance; informally referred to as "The More The Merrier" (capitalization makes it official) clause.
Joy can only be stolen with one's permission, but not stored, except in trace amounts and paltry recollections.
While joy can be killed, it cannot die.
Joy is simultaneously unquantifiable and unlimited, accessible to all, at the intersection of Here and Now.
"While joy can be killed, it cannot die." : )
