(I thought Haifagirl was joking, actually…)
No one would ever suggest a shidduch for a girl if they
knew him to be anything but a frum adult male Jew.
While one might be able say the same about middos, people are
usually aware when someone is not one of the aforementioned,
but they may not be aware of someone’s lack of good middos,
so you’ll want to look out for that yourself.
