I think calling it a negative is overstating it, but it's what people go to because we don't really have a word for it. It's more like, an "I'm-putting-my-foot-down", don't argue with me, extra bit of finality. Kind of like a parent telling something to their kid with an air of authority, or the kid shutting down when the parent isn't accepting what they're saying.

For me, this started in the early 2000s with SMS, and really only applies to chat-style messages, which is why I have no problem using periods here.

Or it's like you're ending a sentence the way you always do. I think it's like that.

You have it completely backwards: "the way I always do" is chat-based. Has been for over a decade, even at work, where we barely use email. HN is the exception.

Someone explained to you something you don't know, and you respond like this. Shameful.

What was explained that I haven't encountered before? My original post in this thread clearly states that I have come across the phenomena before, and that I have explored it with multiple people.

You assume someone doesn't understand something, because they hold an opinion different than yours. And you judge moral character for making a joke online. And elsewhere in this thread, you are attempting to police my behavior and tell me when it is okay for me to speak.[0] Despite this, you clearly feel yourself to have the moral high ground over me.

Regardless of what you might think or believe, I evaluate my prior replies in light of every response, even yours. Will you evaluate your officious tone and domineering attitude?

[0] Specifically, not now, after you have determined I do not understand. How am I to learn if a demonstration of ignorance (or at least that indicates such to you) is a prompt to stop talking?
