By “for a shidduch,” did you mean to date or to live with their husband?
One of my teachers-in-life always tells us not to go upside down near the mirrors. He stresses this in every group class. I avoid the mirrors because I’ve learned to trust him and his experience.
When I took his training, he told us how someone fell into the wall and two approx 10×6′ mirrors came shattering down.
Context, please.
