ahhh where to start
Firstly, AFC's think that when talking to a new HB that they only need to imput 50% of the conversation and the other 50% will come from the HB. They are wrong.
Most HBs will only give about 10% into the conversation until they become comfortable talking to you (its sort of a test to see how intelligant you are and also to not come across as sluts to their friends). Now, if you only give 50% and they only give 10%... whats gonna happen? 40% of the time its gonna be an akward silence

bad times
AFC: so where are you from?
HB: london
AFC: whats it like there?
HB: nice
AFC: ...........................
HB: i gtg now, LJBF.
What was wrong there? boring, predictable questions.
Madals: so, where are you from?
HB: London
Madals: Thats really cool, i used to love london as a kid. Especially the science musem, i was a bit of a nerd *laugh* Have you ever been there?
HB: (i will make this hard for myself) No
Madals: really? you really should go some time. So if you dont do that then what did you do?
HB: i went to clubs
Madals: I have never been clubing in london, some1 told me its really overpriced and rubbish, whats your opinion on them?
HB: they are ok. (notice she still wouldnt be giving much?)
Madals: (now showing she has to put in more input) What sort of clubs did you normally go to? Personally when i go clubbing i like the more exclusive locations, you know the quiter places with lots and sofas and stuff..
HB: well.... blabalbalbalbalbalblab
Get the idea? be persistant, afk interesting questions. If you really feel a topic has gone dead move on, make a new topic. Dont try to squeeze every last little bit outta 1 topic if it isnt going well. Talking in depth to some1 about 1 thing is good sure, but talking to some1 about lots of things will make the HB feel she has much more of a connection with and knows you better

Good times
