sometimes, someone will say something like “it’s all in the past”

what is the past, exactly?

where is it?

is it out there in some other dimension?

is everything that ever happened or ever will happen out there somewhere?

what is the future?

is there such a thing? or substance, or domain, or whatever category it belongs in?

what is memory then?

the memory of a thing is clearly not the thing itself. they say every time you recall something, it comes back just a little bit different.

maybe a memory of a thing is like the impression left by a passing footprint on dew moist grass.
