Okay kiddo, today we are going to talk about something called "mediopassive voice". This is a way of talking and writing that shows when something is happening to something else, but it's not really being done by anyone on purpose.
Let's say you have a ball that you throw at a wall. When you throw the ball, you are doing something on purpose. But if the ball happens to bounce off the wall, that's not really something you did on purpose. That's kind of like the mediopassive voice - it's something happening, but it's not really being done on purpose by someone.
In writing or, talking, sometimes we use the mediopassive voice to show that something is happening to an object or thing, without really saying who or what did it. For example, we might say "the window was broken" instead of "someone broke the window". It's like we don't really want to say who did it, but we still want to talk about what happened.
So that's what the mediopassive voice is all about - it's a way of talking or writing that doesn't really focus on who did something, but instead on what is happening or what has happened to something.
