Hey Tom,

Did you hear the cops pulled over Janet Jackson last night?

She had a headlight out.

You didn't read the rest of my posting. Current is dQ/dt, the rate of

Yes, and at a current loop in a standing wave, dQ is positive
for 1/2 cycle and negative for 1/2 cycle. If the forward and
reflected current are in phase at zero degrees, dQ is moving
toward the load. If the forward and reflected current are in
phase at 180 degrees, dQ is moving toward the source. That's
the convention.

You seem to have lost contact with reality when it comes to AC.
Remember the e^jwt term? The standing wave current at a loop
changes sign, and therefore direction, every 1/2 cycle. Current
cannot stand still because dQ would be zero.

You're not getting it again, Cecil. The instantaneous current is
changing with time, but it isn't moving anywhere. e^jwt doesn't
have any space information in it.
