I've been thinking more about my previous words regarding virtual days versus real days. I think the real nub of my gist is that any given day has only one paltry actual identity whereas it can have a multitude of virtual identities.
For example, let's say I go in to work on an actual Wednesday. Yawn. How dull.
what if that Wednesday was just a single day after a break, with a four
day break afterwards? Then that Wednesday is a virtual
Monday, because it's the first day back. But it's also virtual Friday,
because it's the last day before a break. And in fact it's virtual
Maundy Thursday because it's the day before virtual Good Friday which
will fall on actual Thursday. That's three virtual days in one.
3 > 1, ergo virtual days are very physiological.
