A metaphor: This year I had very little time, and found no hatzlacha in finding a mehudar esrog, so I bought a “sealed box” and relied on the the yerei shamayim employed by the badatz that the esrog is what it is labeled as. When I opened it up, it was not exactly a love affair, but we stayed together over succos, and functioned well.
Now if we could develop a sensitive, vetted, no opening, no refund, “sealed box” system for shiduchim ?
