I don't have your full attention. You don't have mine.

If I looked someone in the eye and said, "Hey, I want you to have this apple, okay?" and then gently, underhand-tossed it to them from a few feet away I'd expect most people to catch the apple. If someone didn't catch the apple, I might even kinda judge them, that they weren't really very present in the moment and I guess maybe they don't think very highly of me or my apple.

But if, at the moment I gently toss the apple someone else tosses them a banana, and a beachball comes zooming in from out of nowhere, simultaneously arriving alongside a pineapple and a layer cake and suddenly a 2025 Toyota Corolla with a bow on the hood rolls into view (and deep down they've been desperately waiting for a pizza, which was not one of the items among the onslaught)...I would not at all expect them to catch my apple.

I would hope they're okay. I'd even feel a little bad for contributing in a small way to it all.

Sending any sort of digital message is like the second scenario, not the first.

Tech Tip: You can turn off Slack '{person} is typing...'

Preferences->Messages & media->[ ] Display information about who is currently typing a message

Small one, but amazing. Your keystrokes in the text box next to my name are none of my business. I'll see your message when you send it to me.

Honestly, the {so-and-so} is typing... what even is that? How is that ever helpful information?
