Esoteric Chat

I don't know of any books that are considered the definitive source for etiquette when texting.
I am thinking about things like it being best to have more than 8 words and less than 3 sentences for a first message to someone.
Another one would be sending a message to the same dozen people daily, to establish a reliable friend group.
How would someone even become an authority on this?

word of advice:
don't talk to anyone underage
don't send them pictures of your penis
definitely don't join discord voice chats while drunk driving your piece of shit audi

I think you're better off running your shitty telegram newsletter rather than knocking up Bee on discord

Just be polite that's all
