Re: do traditional professional girls still exist?
This! Don’t assume too quickly about someone without getting to know them or about them.
Don’t assume that just because she wears hijab, she’s a stick in the mud and is going to start saying astaghfar and plugging her ears when she hears elevator music.
Don’t assume that wearing a t-shirt means, she’s a modern club-hopping, booze-drinking girl, who is out of control.
Don’t assume that because she’s quiet, that she’s boring.
The best way to get to know someone is generally in a larger circle if possible when you get to observe them. There’s no “OMG, this is a first date/rishta-meeting” pressure and hopefully everyone, guy and girl act naturally around each other.
If that’s not possible and it has to be a one-on-one date/meeting - it shouldn’t be an awkward set-up. Do something fun and possibly interactive, as opposed to a candlelight dinner. Maybe like mini-put or something like that. It takes the pressure off by making it casual and the plus side is, mini-put should be an hour or less of your life.
