WIY: You said not to use tznius, but I do find that it is a strong correlate. However, even stronger is someone who will talk about her struggles with tznius.
In a dating situation, if a girl brings up something that she is working on in herself, you know this is someone who cares if you see that reflected in her actions (as opposed to just trying to impress the other person with her frumness by not wearing a seatbelt or something.)
Pirkei Avos says Ain Am Ha’Aretz Chassid – if she is aware of small halachos and follows them, I would say she is a Yarei Shamayim. Also if she has a set time every day that she studies Halacha and/or shmiras Halashon.
Females of the CR – do you think this is correct?
Thanks!
