Completely agreed. But unfortunately, at least in the US, logic has gone out the window.I have to disagree.
Kids are quite interested in the personal lifes of their teachers. The younger ones even more than the older ones. I've done tons of internships and the introduction was always the first thing to do. There's a clear patern in the first questions : if I had a girlfriend or if I was married, or had a child. Sometimes even basic stuff like if I had a mom and a dad and if they were nice or strict. Just because that's what they can relate to from there own lifes.
Quite frankly, the young ones cared less for my age . They don't even understand big numbers yet. Age doesnt mean a thing to them, they can't yet relate to that. Someone once guessed me as 50, because I was longer than their own teacher ...
Even once, a kid asked if I was pregnant (the kid had a pregnant mother and didnt fully understand the concept, so he kept asking everyone is he or she was pregnant). Young kids have no idea what is and isn't approriate, so they speak and ask very freely and directly. That ' social compass' is full in development.
The older kids, certainly the girls, get a bit more giggly and sensitive about personal questions. They have developed so much more social skills and understanding of socials paterns, so they know what to and what to not ask during a first introduction. The older ones had a clue about my sexuality after a while, but knew it was a sensitive subject so they didn't dare to ask directly. They try to hint at it, but backed off if I wasn't showing an open attitude about it.
It is not a standard school subject that is taught or remembered like that. It might not even be a class wide thing. But the personal interactions happen all the time. I'm quite sure that despite the differences between the USA and the Netherlands, a teacher in the USA also has tons of interactions with students apart from their general class instructions.
This is also logical: young kids have a very narrow social network when they are young. A teacher is often within the top 5 of adults they have daily/weekly interactions with. A teacher a new adult to learn from, but also a person they are curious about. They wonder if that adult is the same as they adults they know. They try to find similarities.
