If I’m with you, and we’re talking, and your device dings or rings, and you decide to stop talking to me and focus your attention on your device, that’s fine, I got a lot going on too, I get it.
But if you don’t excuse yourself, I’m peeved.
Now let’s say it’s super important and my feelings of neglect are the least of your worries, I get that too. I’ve got kids and other important things going on, and maybe I’m not as polite as I can be at all times as well.
But if after dealing with your super important issue you scroll through your Instagram feed, well, then I’m peeved.
