I hate it so much. I always say "I just assume you all see my screen. As you can see...". Screen sharing works in what? 99% of cases? We do not need to ask if everyone can see my screen and let 1-10 people answer that stupid question every time. The modus operandi is that this software works in the vast majority of cases and the recipients just need to know that I started sharing my screen and that it will in 99% of cases work just fine. Let them speak up for the 1% of times where it does not work.

I am also a big fan of ending my emails with "A response is not needed". Stop sending me replies with those stupid one line emails "Thank you so much for sending me what I asked you for.... bla bla". Not every emails needs a response.
