First time in Southern hemisphere (RSA, in late July i.e. winter): come from the airport, settle at the Jburg hotel, take a bit of a walk and find a nice restaurant, decide it's warm enough to sit down and have a beer at the terrace.

Choose a nice table that'll be in the sun for the next hour... and 5 minutes later realize that yes, the sun moves the other way round than in Northern hemisphere.
