I'll start off with one, Being upset about a breakup that happened hundreds of years ago.
Edit 1:
- Heath death of the universe, Death of the sun, etc, does not count. I feel like focusing on this is an overused point.
Edit 2:
- Loneliness does not count. I feel like we all know immortality means you'll miss people and lose them.
IDK, I feel like researching for supporting evidence of a theory you already know is correct would be much easier than researching to try to piece together a theory from no information. I think you could put the truth out there as credible and well-regarded theories, even if there are incorrect alternative theories that people also have to consider.
