I don't have approach anxiety anymore, but what i do have is a small talk anxiety. Example, Yesterday i went out to a reocurring social event in my town. So there were two chicks that i noticed. One was pretty damn hot so i decided to approach.

I told her, hey i see you pretty often here, you really enjoy this event? She said , yeah i do. I said nice, my name is Nad, what's yours... She replied. And basically slowly conversation went into the deadend.

When i know a girl and i am on a date, i can perfectly bla bla. But when there's a girl i know nothing about, my bla bla motor stops working.

How do you improve this? What do you small talk with girls you don't know about?
