DH. I was really sad when the second mine explosion at Pike River happened and that there was now no chance that anybody was alive down there. I said something to DH about it being very sad, and he responded:
DH: Oh they were all already dead.
Me: You don't know that for sure.
DH: Yes, because nobody could survive XYZ... <big long technical explanation about mining and gasses, oxygen etc>. They were already dead, they were just waiting for the right time to break the news to the families.
Now, I'm sure DH's knowledge of science is accurate. He's a very intelligent man. But as I explained to him later that day, it's not nice to phrase your theories as absolute verbatim fact - it's kind of a conversation stopper. Plus his theory was also making insinuations on the characters of the rescuers and authorities involved. He realised what I mean. The thing is, it's great to share a theory or interesting information, but he often makes up his mind about something and refuses to actually discuss it. To be fair, I'm too far the other way and like to speculate constantly about hypothetical scenarios....
