Mr.Stranger that sounds like a stressful experiment, I think a lot of people would not thrive in that environment.

Lots of people (men and women) feel happier developing friendships with people before romantic relationships, that whole 'approach a stranger and get her number' sounds quite intimidating.

Thinking back to my young years I never once gave my number to someone I just met, although I was asked a few times - the whole prospect felt too scary to me.
