Back when I was going to public school,we generally knew nothing about the private lives of our teachers,other than they were married. Even then we only knew that because they
were wearing wedding rings.
And I honestly don't remember anybody caring or even thinking we needed to know anything about their personal lives.
The only exceptions were kids that went to school in remote rural areas,where everybody knew everybody. You would run into them at grocery stores,movie theaters,etc,etc,etc.,but that didn't mean you were friends. You were children and they were adults,so you said "Hello,how ya doing?" and moved on.
