So, I Have That Going For Me...
(Three Slices of Pi)
Post-Script: I suppose if a person lives long enough, one's assemblage of things in life begins to resemble a collection, of sorts, which is distinguished from a mere pile of junk by some semblance of organization and valuation. And when one passes on to their reward, it is left up to their heirs to decide what's of value and what's best left for others to sort through.
