Halevi, in your opinion. That is a mentchlich conversation and there is nothing untoward about it. There is nothing too personal or inappropriate about it. It is not someone who he stopped in the street, it is a neighbor who’s mother, father, sister or brother could have been in the window or on the porch. It was in front of her and basically his own home, where his parents could have seen as well. No big deal. Again, menchlich and nothing to be hidden or to be ashamed of.
Maybe if more people would pull their heads out of the sand and out of the shmutz, kids would have more healthy lives and there would be a lot less OTD kids we have to deal with. There is nothing wrong with mentchlichkeit, something the Yenta lacks.
