I suppose one shouldnt be totally upfront in the sense of telling someone your life history the first time you meet them
Thats hard, cos if i fell i can talk to someone------
Also, if you really fancy someone,then its a bit too easy to start imagining things you have in common, and fantasising about the future
BUT
having said that
i think phoning someone after a night out, well, there =s no point in playing hard to get then
