Well, I'm not saying to just ask them question, what I said is how to converse with someone. Normally, how would you react to someone who abord you and talk about himself? About 15 seconds later, you'll tell him STFU and go, rigth? People like to talk about themself, so I just suggest to abord someone and to be perceive rigth, talk about them and then, when the link is there, perform magic. If I red correctly, he have difficulties to talk to stranger and don't know what to say. I tell him: ask question. After that, you can converse on a point that both of you like. But if you begin to talk about yourself BEFORE establishing this link, you wont go anywhere. That was my point. Sorry if I wasn't clear, english is not my mother language
