People who can’t do better have a totally twisted view of reality. They do things which are incredibly silly.
When you know them you don’t bother to explain why it is so stupid to do this or that. You shrug.
For example, take Facebook.
There are people who publish photographs of themselves every day. You wonder to yourself why they are being so ‘out going’. Yet, they will lock off ‘messenger’ so that they can not get private messages or have video calls. They will lock their phones so they can not receive calls.
Now, if they were ‘secretive’ they wouldn’t be showing you their cleavage. If they were private you wouldn’t be shoved into their lives.
These people have a twisted view of reality, so leave them to it.
