LOL... I’ve spent years in places it’s a 2 day drive over rough country to get to the nearest phone. It’s very, very easy for me to adjust back to living that way. Done it a couple few times for various reasons.
What’s difficult, for me, is trying to live INSIDE modern 1st world life without phone/internet. (Did that for 2 years because of a stalking issue.) Because everything is so automated & electronic, these days. Some bills in my city can’t even be paid in person... or by mail... anywhere. They have to be paid electronically. Ditto a lot of the “social” stuff. Either it’s entirely online, or Facebook / evite/ various Apps/ etc. are the only ways to hear about people getting together. If you want to stay in touch with people? You have to have an account with whatever social media platform the group uses. The secretaries at my son’s middle school (I picked up hard copies of the info emailed out to parents, or was posted on the school Facebook page), once they got over being shocked at a parent actually coming in, start reminiscing every time I came in about how parents used to be at the school so much more, and notes pinned to tee-shirts, and PTA meetings held in the cafeteria, etc. It’s all done online now, except a once annual orientation (which includes account & password creation, and group permissions, etc. for all future school contact).
