I just don't see why talking to yourself loud would in any way be preferable to just thinking, unless you have trouble thinking. I guess it’s ok if you just do that when trying to wrap your head around some topics when trying to understand them. But my roommate (freshman in tech uni) is currently watching some anime shit and he is in fact saying "wow I didn't expect that", "YEAAAH I KNEW she was the honey eater, YEAH", "wow that was a dick move", "haha they found a shitty person for that job", "go do that you bitch" and just randomly "wow", "oh", etc. out loud. I just don't understand. Can't you just, well, say/think about that to yourself in your head? Is it somehow going to change if you say that loudly?
