I am not sure this is possible without extensive training. I once had a an assignment to meet with someone I had come to despise. But my face cringed just at the thought of sitting across from this person. So before the meeting I put a fake brace on my left arm and explained that if I look mad or frustrated it was because I am in physical pain. I was able to get through the interview and get information he might have withheld had he sensed I was hostile towards him.

You have a point. First there were words and punctuation, then the punctuation agglutinated into emoticons, now we have Unicode emojis, but peaches and eggplants are obscene, white space is significant, periods are rude, ellipses are ominous, and at-signs are sphincters.

>“Why would anyone use a period in an IM or text? Using periods in informal communications is rude.”

>“What millennials really want to know is why boomers sometimes end innocuous statements with three dots. That makes everything sound ... ominous.”

>Another millennial of my acquaintance told me something else: The casual use of an @ to mean “at,” as in, “Are you going to be @ the office?” is interpreted by millennials as a deep offense: By code, you are calling them a sphincter!

I'm in the cohort described in the article, and I call BS on using periods being rude. Omitting periods when sending multiple sentences makes your message jumbled garbage.

Unlikely; emotional expressions seem to be innate and hard-wired into the brain, hence the fundamental similarity between emotional expressions of groups separated for tens of thousands of years.

All of whom are connected and changing together now.

Also; hard-wired by who or what other than volume of use?
