When I visit the southern hemisphere I’m always struck by how weird it is that the sun is going the wrong way across the sky. It really messes with my sense of the time of day.
It’s going east-to-west in both hemispheres, that’s for sure. However, in the northern hemisphere the Sun goes from left to right, and in the southern from right to left, when you’re looking at the Sun.

As pointed out below, it's because in my normal latitude (south UK) the sun moves from left to right (as you face South) and at a similar distance below the equator, it goes from right to left (as you face North). So at home when I look at the Sun I know that a couple of hours later it be quite a bit to the right of where it is now, and I can use this to assess where shadows will be.
Seems like this would only be true if you’re above the Tropic of Cancer and then comparing to below the Tropic of Capricorn. Between those zones the left/rightness of travel would change dependent on the season.
