What I should do back in the Days was if I fancy somebody and if they fancy me then we will just chat for sometime, getting to know each other...Then ill ask her if she want to video chat on Skype or MSN...if she agrees then it's cool,but if she disagree then my instincts will tell me *Something Fishy*...
lol usually after that she just offline when she she's I'm online ect...I'm talking about my past experience...
