OK, so nobody likes her suggestion. Any others?
I have no kids in, or imminenetly approaching this stage in life, so have no first hand experience. Empirical evidence however, coming from redting shidduchim, shows that just getting someone to agree to see someone is rather difficult. Many assumptions and leaps of faith about other peoples families, attitudes and behaviors are made based often on heresay and (usually biased) judgement of other people.
Nanacy Reagen said, just say no, in shidduchim we have taken it to an extreme.
