No, that’s not what this is about.

It’s commenting on the fact that sometimes abuse survivors share traumatic stories as if they’re normal or even fun, when compared to a normal upbringing they’re actually incredibly depressing or traumatic stories/memories. Because to them, those stories were the normal seeming parts.

So sometines they’ll do this with no sense that it’s a traumatic story - because it’s far from the worst things they experienced.

When this happens, it has the mood of the two characters in this gif. So hope that explains it for you.
