A favorite opener of mine
On the street near a shopping area is best gently touch a girl on the shoulder who is wearing headphones then say straight? Left? Right?
They'll say something along the lines of whaaattttttt?
Then you say oh I asked you where the next _________ is
And then lead into a conversation there
I always go agh I'm not from around here or I'm new to the city can you point me in the right direction
Then move onto what are you doing later etc etc
Variations and suggestions are welcome
