ask if if he knows where someone or something is, then go to the place or person he suggested or pretend to-come back within a few mins (not long) tell him you found it and thanks. then ask what hes doing or what that is?? something liek that, of which he knows the answer to and be intrested in him. He'll talk back because he knows the answers. And then maybe ask for a contact method a few weeks later. You'l be fine!im always intrigued by people like that, but dont suually fancy them..at that point. Just act like you got something to do or somewhere to be so he doesnt get pannicky at first and doesnt feel to much attention is on him. Good luck!
