I ride a bicycle to and from work across town. I often do approaches like this. Ride up quietly to about three or four yards behind target, get off, she doesnt notice. Walk with bike. Ring loud bell like hell. Targe turns suddenly in case gets run over. Looks at me pushing bike. Laughs, eye contact, laugh back - your in.
My problem is that I often walk only a short distance with these chicks because they are going one way, and me another. They are usually on their way to work, on their way back or off to the station or car park or whatever.
How can I turn up the heat real quick and get them to give me their number?
