I agree. There is no point in lying, as the facts are not going away. Age, size, family, ect are too verifiable. If you want to fudge, do so (within reason) when talking looks or personality.
But some facts are just what they are. They are unavoidable, and are best dealt with up front.
I’m on the verge of redding a shidduch, and the girl is (IMHO) simply fantastic. Looks, brains, vigor, everything. Except yichus. And when I meet the boy’s parents, I’m going to tell them, the girl has the same yichus that Sarah and Rochel and Rivka had. If you can deal with that, we can talk. If not, I understand, but I can’t change the facts, so if its a no-go, its a no.
Eclipse nailed it. If this is the bashert shidduch, it will go past this hurdle. If its not, someone else will be the lucky chosson.
