I have no reason to be in contact with anyone I went to high school with 55 years ago.
As far as current friends they will either be seen in person or by VOICE contact by phone.
No text, we have our phones blocked so we can’t receive them!!!!
I’m actually surprised that more older people don’t use text messaging. Too many concerts and manufacturing plants over the years means that my hearing isn’t the best, especially when there is background noise. Texting also allows a conversation to occur in the “background” without either party losing track.
On the other hand, there’s a definite breakpoint at approximately age 50 vis a vis technology comfort. The reason is pretty simple: video games.
