I've been working my job for about three months now, and during that time I've seen a lot of girls from my old school who I havn't seen in about three years (I go to private school now but work in town). I can usually grab a minute or two to talk to them, but its hard to create instant attraction from someone whos basically a stranger who I know by name. I would like to get a number from one or two of them, but it always seems like it would be a little strange to just ask for it out of the blue. How can I move from the usuall what have you been up to conversation to one that ends in me getting her number?
