Yesterday I found someone who says “question mark” after every question and has apparently forgotten how to inflect their voice to express tone. It was horrifying, but I realized I’m not that different. I immediately think “cringe” or “based” at many things. Even when I’m not terminally online everything I hear gets put on a meme template by my brain. I’m having trouble expressing tone/emotion in writing without visual indicators like emojis or “/s.” I know I’m not alone, what do we do?
I sometimes say "question mark" out loud but then again, I have robo-droid-person autism. For writing, I look at the writings, like diary entries or letters, of the past. For sure, as another person has mentioned, books help, and I'd like to add that directly borrowing/learning from person-to-person texts can give you a good presentation of expression just through text. Also, it might be of help to look at words by themselves, by which I mean that you think of a word and look up a synonym with a connotation suiting the emotion you wanna give your writing. For example, "happy" and "jolly" mean the same but express it differently
Looking at old letters sounds like a good idea. I do love synonyms and could always use more.
