Re: arrange setup
Adding to what Barbie said here and earlier, it is the ONLY acceptable way socially unless you are way head strong and have no qualms in dating and checking out a guy/girl.
What both parties need to do is to gather as much information as they can prior to the visit so that they KNOW what they are getting into. maybe the girl’s parents can share pictures and tell information if they are comfortable enough. Otherwise half hearted visits can be super annoying.
