I look at my parents, both retired. My mom is on Facebook constantly and always talking about what people post. However, I’ve never hear her talk about actually getting together with these people. She doesn’t go do much.
My dad never talks about Facebook. I believe he has an account, but I don’t know if he frequents much. He calls people on a regular basis to catch and schedule stuff… golf, pickleball, lunches, etc.
My mom has the illusion of connection via Facebook. My dad has actual connection through actual conversation. While he didn’t meet up with these people in-person as much during the middle of his career and while raising kids, he still made it a point to keep in touch, and it’s paying off for him in retirement.
I guess the question you need to ask yourself is are these people really friends if they can’t make time to catch up from time to time outside of the walled garden of Facebook? When you say they don’t have time, are you waiting for them to reach out, or have you reached out to them? Understanding people are busy and reaching out, without judgement or expecting that it’s “their turn next time” seems to be a key to maintaining actual connections over time. At least that’s what I’ve seen with my dad.
I think my dad did reach out to someone on Facebook recently. Someone he knew freshman year of college who kind of disappeared. He very quickly sought to meet up in person for lunch to catch up, rather than do it through Messenger. Know the guy texts and calls him all the time, no Facebook required.
