Don't look up. They are in a private pool transparent across two buidlings... no one has seen them right!
So just to be clearer what we see here. We can observe here rich people in their natural habitat that value their privacy. Since they don't like to mingle with the rest of us mortals, they like to live high up and find ways of not touching ground. So they build bridges between dwellings. But I am very confused with this one. Why would you want to have water in a bridge. Maybe they are trying to do 2 things at once, cross a bridge and a take a bath. This is a very clever way of prioritizing our resources. Amazing!
