People stand on their own set of rules and principles when doing shidduchim. What one person considers foolish and stupid another considers absolute unyielding. There are no rules in the shidduch game and unfortunately parents miss wonderful opportunities and waste years of their children’s lives while doing this.
Yes of course, parents have to be careful and do what they think is best for their child. But they also have to realize and understand that their is another partner in the shidduch game/process and that is Hashem. And that every shidduch presented is presented for a reason. Hashem put that idea into someone’s head and that is why that shidduch was redt! That great learning boy those parents are selling may one day decide he had enough and he can’t do it anymore. Hashem has a very interesting sense of humor and he also tests people in different ways.
It is truly unfortunate that WE as a whole don’t realize that and understand that, and we are way too quick to judge others for minor and incidental issues.
