So, online dating, how do I choose who to stay away from? Why do they all ask for your phone number straight away coz they don't want to play email tennis?! Are they pushy one night standers or do they want to meet straight away as it's easier to see if each other clicks in person. Want to give them the benefit of the doubt or is there a rule I don't know about not meeting up with the ones who want to meet after 2 emails!?
