Draw circles in the sky.

When you see the Moon due south from you, north (on the moon) is up, just
as north is behind you where you're standing.

When you see it rising in the east, north on the Moon is to your left,
same as north being on your left when you're facing east.

When you see it setting in the west, north on the Moon is to your right,
same as north being on your right when you're facing west.

In other words, in twelve hours, you're upside down.
