I’m Latin American and obviously of Spanish descent: I think, by own experience, that this comes from one or two generations before having LIVED in houses with say 3 or 4 siblings: you are used to shout to one another, not to think twice before speaking in the coexistence, etc. Well life in our hispanic countries used to be like that, say, until 45 or 55 years ago. When after all the above you move to a big city into a tiny apartment, y ou are just not used to the new rules of the game and you were already formed, so it is hard to change. And then, what is about, life? To have a good time if you can. So as everybody is laughing, talking, listening to music or even dancing, the neighbors don’t complain: everybody lives the same.
