A possible bad event which becomes cyclically talked about, but there are no actual solutions that are proposed.

## Narrative example
Tom is very worried about a comet hitting the planet and wiping out civilization. Each time he and Jerry have a conversation or try to plan anything, the conversation struggles to move forward because Tom makes everything about the comet.

It's like a virus because the longer this goes on, more people will start to worry about it too. Either they'll get worried about the comet, or they worry about attending meetings with Tom since he won't stop talking about it.

No matter what anyone does, it seems impossible to address Tom's concerns. Any solution that's proposed is immediately shot down or rejected.
