Nice, same headphones as me!
I don't have children, but have a very big family and have grown up around children my whole life, looking after or being there for my cousins etc from when they were born. And I must say, parts of this game had a pretty profound effect on me, without much really even happening.
In particular a house in Bills area that had children's playrooms in it, notably this little jigsaw mat unfinished in the living room, and most of all the nursery school in the sewers at the end. Reading those letters and learning of what likely became of those poor children's fate. Honestly, was like a punch in my gut. For a while I was kind of left sapped and hit hard. I remember the first time I played the game I just paused for like half a minute, having to give myself a few seconds to come to terms with the scenario implied. First time a game has really had that sort of an affect on me.
