This is what I call a load-bearing "just". People don't "just". Getting people to change their workflows and habits is difficult. And they certainly won't do it

This is what I call a load-bearing "just". People don't "just". Getting people to change their workflows and habits is difficult. And they certainly won't do it for the single person who decided to opt out of common communications channels. It'll be up to you to actively maintain that relationship. After all, you're the one that opted out of the social contract. I've encountered this everywhere, even with myself. I'm bad at keeping in touch to begin with. Anyone decided not to use normal means to communicate with me are likely to get missed among the hundred plus other people I know. I'm not on Facebook, so I'm left out of the majority of my family's communication. The only reason I know anything is I regularly call my parents to get the summary. (It's also a good excuse to call. We always have something to talk about.)
