To the entire thread below this, to understand what people around you are doing, you need to understand that there are elements of human communication in which people are deliberately ambiguous. (Not always conciously, but quite deliberately.) It's a huge element of all of the standard human courtship rituals (all the real ones, not the ones that people claim to be using), it's used to speak in plausibly deniable ways for everything ranging from crimes to minor social incidents. The ambiguity itself is part of the message being sent.

Most people actually are very precise in their texts and speech. It's just that the message-carrying layer isn't in the denotations or even the connotation, but the way in which connotations are used. (Humans are amazing things at times.)

(I'm practicing. I have two high-functioning still-pre-teen autist children that I fully expect to have to convey to them an explicit model of human social interactions as they get older. I'm already having to start; the younger really, really wants to be funny. We're actually making some progress. Not, I mean, necessarily a lot of progress... but there is some progress. I'm not saying everyone below is autistic; I have no ability to judge that from here. I'm saying I need practice trying to explain this stuff because I personally definitely do have some autists in my life who will have this problem in the future.)
