Yeah, see it's that old electron flow vs. current flow thing again.  I
need to remember to whack myself sharply on the head right before engaging
in thoughs about current flow to remind myself to forget about the
electrons.

Tougher to forget about it now, though, when ground is often labeled "Vss"
since it's the source of electrons.
