It all depends on trust with me. I'm cryptic around people I don't really trust, but if I trust someone enough then I'm not looking for anything sinister in their words or actions, as instinctively I feel safe with them. I feel safe with everyone on this site, for example, so it's not very easy to upset me here.
But if people have a history of causing upset for me, even if it's subtle, then I can become paranoid and anxious whenever I'm around them, and I start imagining them plotting against me. But fortunately I trust more people than not, as there has to be a proven reason as to why I don't trust them. On the very rare occasion I have made mistakes with being too cryptic about the wrong person, but misunderstandings do happen. We're only human. NTs can get it wrong too, like sometimes they can mistake a shy person (not necessarily an Aspie) for being peculiar or unfriendly.
I made a mistake today, a friend at work pointed to a pack of biscuits and said that he'd got them for me and another friend. I thought he'd meant he'd got a pack of biscuits each for us and that maybe the other friend had taken her's, so I said "thank you" and without thinking I slipped the remaining packet of biscuits into my bag, as I know it can be rude to reject a gift. But later my friend asked where the biscuits were, and luckily my social instinct kicked in as I suddenly figured out that the one pack of biscuits were for me and the other friend to share, so I said "oh, I took them into the office, for safekeeping", then I said, "shall I bring them back in here?" And I went to get them from my bag without anyone seeing. I'm glad I got away with that little error lol, because I hate coming across as greedy, as greed was not the intention.
