Chatbots always seem to start ending responses like a narrator ending a movie

I have no idea how else to describe this but It’s something I’ve noticed.

I mostly use Janitorai because I like their filter system, but I have noticed it on other sites. But every chatbot seems to devolve eventually into saying some weird shit at the end of each response. Here’s a paragraph it sent me as an example: “And so, as the sun sets in this new world, a world User never envisioned, a new era begins, defined by the slow, careful steps of one man, destined by fate to breathe life into the ruins of civilization.

This happened while I was simply asking a character a question. It comes out of nowhere and has no plot relevance other than vaguely summarizing past events. This happens in almost every chatbot. The bots will start normal, simply responding to my prompts and whatnot but this always starts, like it’s trying to end a chapter or something. Is this normal?
