Stand on the North of the Earth and look at the full moon. It seems to be one way up. Stand in the Southern Hemisphere and it will be the other way up. Basically one view is 🙃 upside down compared with the other. In fact if you are near the equator the view will be at right angles to the normal view. I think some people see the moon as a boat crossing the sky when it is waining. ie a young or old moon. When you only live in one Hemisphere you dont realise that other people can have a different perspective. Trying to put yourself in there position can change the way you look at life. I’d love to go south of the equator and see the Southern Cross and the greater and lesser Magellanic clouds (small galaxies near our milky way galaxy) which are not visible in the North.
