Theres an underground hipnosis trick called strings.
The basis of which is as follows:
Ask the person a variety of questions and listen intently to their replies ie:
Where do you like to hang out?
What sorts of people do you find interesting?
What sorts of subjects interest you?
Do you have any hobbies?
This kind of puts the ball on conversation in their court, any answers they give, just tie an imaginary knot around them with an imaginary piece of string and hang them up in the left side of your vision, just dangling.
When the ball comes back to you, you’ve got 4 or 5 items of conversation that you know are of interest to that person. Just pull the first string and chat some bollox about that subject like:
“I’ve heard that such’n’such mall on dale street is a good place to hang out, are there any good coffee shops to hang out in there?”
If you don’t get anywhere with that one, just pull the next string and chat some more bollox. Eventually after speeking to a number of people, you’l have loads of info about different subjects that you know people will find interesting because you already know that thats what they were interested in.
Then the next time you go out, before you try sparking a conversation, hang a few strings with various topicks that got some good conversation the last time you went out and see what happens.
After some time and practice you may find you’ve got 10 or 12 strings dangling in front of you.
Also, don’t be afraid to write down and memorise the things that interest you, and put them out there, or even put your 2 pennies worth in with a conversation your friends are having, even if they don’t agree with what your saying, or your point of view, its your opinion and believe me, its always worth giving.
Just look at Fluther.
