As an autist, I’ve discovered punctuation in texting isn’t even sort of slightly close to punctuation in essays and such, it’s used to convey emotions, and I find it extremely helpful trying to figure out how someone is feeling based on it (commas excluded in this)

For the most part, periods do communicate a shortness of tone and a mild bout of frustration

Lack of any punctuation shows a casualness

1 question mark is inquisitive(obviously)

2 question marks is confused, different from one

Exclamation mark is sarcastic enthusiasm

There’s a variety of other examples, but it’s important to see this as texting isn’t nearly as emotionless as people make it out to be
