a period at the end of a text

For parents and educators
Not slang, but a common source of mix-ups between parents and kids. Your period probably feels like a frown to them. Theirs, if they use one, may mean they're actually annoyed.
Where it came from
Research at Binghamton University in 2015 found one-word texts with a period seemed less sincere. Linguists say texts without one became the neutral default.
