This one is credit to Style. I never heard it mentioned much but I've been testing it out and it's having some cool results.
I read somewhere that when style was just starting out he would ask people this question, purely out of curiosity about relationships, marriage and kids.
"Hey let me ask you guys something really quickly: If society didn't have all these rules and there was no pressure to do things like getting married, and you didn't need someone to take care of you when you got older. Would you still get married or would you just follow your heart and do what make you happy?"
A lot of chicks give you some weak answers like just "yea" or "no". I realised it's because it's a sort of deep question. So after the weak answer I'll get them to talk and think about it more by making a statement about it:
"That's interesting. This has been on my mind since a friend of mine from India went to visit his parents and they've been trying to set him up on an arranged marriage!" - This one's genuine to me. It gets them talking a bit more.
"Oh you know what's pretty cool? Most guys tend to say they would never get married but girls say they would."
Pretty much however you want to carry it on. It's an opener that can keep people talking. They love relationships.
What's cool about this is that in the girls that I number closed, when talking to them later on they would bring it up. Saying it really got them thinking about who they were and if they're really happy etc. Easy way to build a strong emotional connection
or a shallow one if you just want to get laid
