One of the companies that I worked for was a university. It was lots of fun to work and some very dedicated people worked there. One of the people who I helped was a mature Jewish lady who I’ll call Jana.
“So the problem is that it does X when I want it to do y,” Jana said.
“Oh, no problem. Let me fix that.” I said.
While I was working I was making small talk and somehow I made a joke about this problem not being kosher. She smiled and asked, “Do you know what that means?”
I said sure. “Kosher is confirmation to dietary laws or religiously pure.” She seemed surprised.
“You know more than my son,” Jana said. “He isn’t observant. It is nice to see other people who know.”
“Well I’m open for adoption” I joked.
Sometimes people say that things they learn they doubt they will ever use. To me, it isn’t a matter of using or not using stuff. Just being familiar with something is enough to make someone feel special.
