Facebook can’t accommodate old geezers who want things to make sense

“Obviously, logic is for wusses!” I said to my wife.
“Facebook can’t accommodate people like me who want causality and reason.”
About a month ago I messaged a question to two dear friends via Facebook; they have Facebooks themselves and use them extensively.
One used to work at the Mighty Mezz as a photographer.
Her husband works at MacShack, and set up this here computer I’m using, an Apple MacBook Pro laptop.
Facebook tells me they’ve responded, but can I get their responses? —And I value their opinions.
My Facebook profile-page has a “Message” tab. I clicked it, and was shown my entire message-chain, which goes back eons.
It included earlier responses these people had rendered, but not their most recent responses.
NOW WHAT?
Facebook is always doing this, that is, not making sense.
I looked at my wife’s Facebook on her own computer. It has the same “new message” tab I have, but also a message-tab on the left I don’t have.
At which point some pimply mohawk-haired techie from Facebook weighs in and tells me to change my security preferences.
Um, GUYS; I had that tab before, and it disappeared!
And I haven’t touched those preferences since I set up my Facebook years ago.
Which leads me to conclude — awful temerity and unmitigated gall and horrific audacity — you guys vaporized it yourselves; or more likely, some change you did inadvertently vaporized it.
Every time I fire up Facebook it’s slightly different.
Used to be I could search graduates of my high-school class, but no longer.
Similarly, my college class, also no longer.
And every time I fire up Facebook, it’s suggesting “friends.”
PASS! I’ve given up! Make a new “friend,” and never hear from them again.
I don’t need 5,000 “friends” I never hear from.
But I could use the advice of my two dear friends, people who are actually friends, as opposed to Facebook “friends.”
But Facebook won’t allow it, or has constructed some kind of unfathomable wall I hafta jump.

• The “Mighty Mezz” is the Canandaigua Daily-Messenger newspaper, from where I retired over five years ago. Best job I ever had — I worked there almost 10 years. (“Canandaigua” [“cannan-DAY-gwuh”] is a small city nearby where we live in Western NY. The city is also within a rural town called “Canandaigua.” The name is Indian, and means “Chosen Spot.” —It’s about 15 miles away.)
• “MacShack,” east of Rochester, NY, is where I’ve purchased most of my computer equipment over the years, and it does repairs. It’s a purveyor of Apple Macintosh computer equipment, but not an official Apple store.
