I have been away at a nice country house hotel with my husband to celebrate our wedding anniversary. It's the sort of place where guests use the sitting rooms in the evening, have a glass of something and chat in front of the fire - or just read, etc.
We met a lovely older couple and enjoyed their conversation and the husband's zest and enthusiasm for discussion. He appeared to have a lovely and kind way of talking and enquiry. He had recently been very ill and we understood from the discussion that he may have had a "near death" experience - although having only just met them, didn't want to discuss further.
The final evening after dinner, we all met again in the sitting room. This is where the very strange encounter happened and I am left a little reeling and wondering if there was anything I could have done to handle it better. My husband and I were sitting in the corner chatting to the couple, the last people left as others gradually said good night. The chap's wife went up to bed and we were left talking. The evening before, the chap had said that he would pose us a conundrum to think about and to answer at breakfast time, which we had thought was another "conversational opener" as we had had some good chats about various things (history and art, not religion and politics!). He had asked us to think about the phrase "nothing comes from nothing".
Left alone with him, he asked us what we had thought. He then became very heightened emotionally, launching into a very strong speech about God, hate, love, and that he had a duty to spread the message. Some of the things he said were quite disturbing and at one point he stood with his arms out, discussing the crucifixion in horrifying detail, then talking that he had "seen God" and how terrifying it was as God cannot look upon sin. He was very upset and it was hard to deal with him - we were also on tiny chairs, so getting up was a struggle and he was hugely looming over us. There was no point arguing with him as he wanted to spread the message of his point, and tbh we just wanted to finish what should have been a celebratory evening in peace and quiet, rather than prolonging it into the night with a religious argument.
There was no space to say "come on old chap, it's late, let's all get to bed" as there was no space in his tirade (wrong word but you understand) and we were strangely worried about offending or upsetting him. We let him play it out and he did eventually go off to his room and wife. I've never been speechless before!
I've never been in such a situation and it felt like being in front of a fire and brimstone preacher - but also in front of a chap who is staring his mortality in the face. I wonder if he had had some sort of near-death revelatory experience. It has really unsettled me - not sure why, and was so at odds with the older gentleman who was standing as ladies came into the room, opening doors, etc, and discussing other topics politely.
What could I have done to diffuse or manage this better?
