There are also people who don't know how to type multiline text. So, they type "hi", send it and immediately continue writing their actual message, possibly with multiple parts separated into several messages instead of single multiline message. So, they destruct their recipients by doing this, since one needs to wait until the whole message is written before starting answering it.

I send multi line messages all the time and I frequently accidentally hit enter before I’m done. Then I have to rapidly make edits and save them, hoping everyone sees the frequent updates and realizes messages is still a work in progress. There has to be a better way.

worse are people who wait for a response before writing the actual message

i have not as yet sent someone https://nohello.net/en/ but i've come close

Honestly I don't mind this si much because it means the rest of the opening is coming along soon. The real issue is when someone slacks me "hi" or "you there?" and I am doing something or in a meeting, then see it 30 minutes later and reply but they're not around to tell me what they wanted.

I have a person in my family who does "..." typing for 15 seconds to 5 minutes just to say "Okay, if you're busy, I'm going to the grocery store".

I didn't need that information.

You just sit there looking at "..." for an indeterminate amount of time not knowing if you can move on.

Frustrating.

And yet I'll miss this frustration so much someday and I never allow myself to forget this fact.

somewhat guilty because I do that with texts with people I speak to often too LOL but yeah not the best practice
