SDD- has Moshiach come in your world? That encapsulates a lot of what the Rambam says will happen with the arrival of Moshiach.
Hashemisreading- agreed.
In terms of whether parents or children know better, I’m biased, since I’m a child in shidduchim. I take care of my shidduchim pretty much exclusively. In my particular situation, I think my parents would agree with me that I understand how to handle shidduchim better than they do.
I’m not saying that this is the norm, or that this is a good thing (I don’t think it is), but just that this is my situation.
