What’s gone never leaves; it fades in the background; hangs around in memory in past seconds, minutes, days, years, eons, but is never gone.
Yesterday passes into today; today passes into tomorrow. Can today exist without yesterday, or tomorrow without today? I say, none can exist without the other. So I posit, nothing is ever gone, but is recorded in the eternal memory of all that has been, is, and ever will be.
As the Sun ushers in the morning after night and the seasons change into each other (winter into spring, spring into summer, summer into fall, and then again into winter), so it goes with everything else, moving from one state to the next, transforming, but never gone!
