Is anyone really surprised that people ask for a photo? It has become “normal” to ask the most ridiculous questions already, this is the next logical step in “looking into the shidduch”.
I cant take credit for this, but I was told that the 1st bachur who asked for a photo, did so because he misunderstood his Rebbe who told him, “the most important thing to look for in a shidduch are her middos”.
