Hey everyone, this is the first advice I give in this forum.
Well I decided to use an opener I saw mystery recommended.
You just approach A girl and say: "you suck".
she would be surprised, curioused, and probably she will ask you why.
At that point you can improvise.
Here is what happened the first time I tried it:
A few months ago I went to A bar with friends, and suddenly HB came and seat next to me.
After about a minute, I looked at her, after 5 seconds she gave me a look back, and I told her: "you suck!"
She said: "why ?!?!" - she was surprised.
I bet nobody said that to her before.
I said: "I've been sitting here for like an hour and you haven't talked talk to me yet"
she smiled: "but you should talk to me !!!" (at that point I understood shes into me, it was an ioi, she kinda said I should hit on her.)
A second later she asked "What's your name ?" (another IOI)
We talked, I got her number, and we dated.
Anyway, just wanted to share this story with you - it worked.
you really should try it good luck !
