I don't know about the rest of you, but I constantly find myself annoying my NT friends because I don't know which topics of conversation are acceptable. There I'll be, talking about something I find interesting, when suddenly one of my friends abruptly changes the subject. The first few times they did this, I was clueless and kept talking about the old, apparently unacceptable topic; but after they changed the subject abruptly and pointedly--to the same new topic each time--several times, I realized that this was their signal that they were uncomfortable with the current topic.
I would like to help others avoid topics of conversation which tend to annoy or disgust people--things which "just aren't talked about in polite conversation". The thing is, there's such a lot of them--thus the figurative "1001" in the topic title--that it would take me forever to run into one of them.
Therefore, the purpose of this topic is to list things which are best avoided in conversation with NT's, or best avoided in certain situations or with certain people (please specify).
These are some of the ones I know about:
1. Talking about death or suicide (as a concept, not an intent) with someone who has been or is currently depressed.
2. Animals involved in common "animal phobias": Snakes, spiders, insects, possibly rats.
3. Anything involving urine, feces, vomit, blood, mucus, or other bodily fluids/excretions. Tears are the only exception.
4. The possibility that a male human being could become pregnant and bring a baby to term.
5. Graphic descriptions of surgery, or, during a meal, any mention of surgery.
6. Autopsies.
7. Descriptions of murders, rapes, or other violent crime.
8. The sexual act in all its variations (exceptions include between good friends of the same gender or, of course, your partner while in private).
9. The undead (exceptions for people who are also interested in vampires or mummy/zombie/etc. monster movies).
10. The organs of the human body, discussed while eating; or graphically with anyone who is not involved in medicine.
11. Cannibalism, human sacrifice, and other socially unacceptable customs practiced by other cultures.
12. Disabilities present in a member of the group having the conversation (unless brought up by the group member with the disability).
13. Torture of animals, such as flinging them out of catapults, cooking them in microwaves, or skinning them alive. Exceptions include young males joking about how much they hate cats. Actual descriptions by someone having committed such an acts are, however, still quite taboo.
14. Discussion, while eating, of eating anything not socially acceptable as a food source; this includes insects and other invertebrates (except for seafood), and organ meat.
15. Discussion of nudity, while in the presence of a member of the opposite sex.
There, that's the ones I can remember... help me out with others?
