How do you get to know a girl who is constantly surrounded by her friends?

proceed like a lion: isolate the prey before attacking. isolated individuals are vulnerable, especially if they have a habit to group up. in order to do that you will most likely need the help of a friend. once you succeed it does not matter in what form you say whatever you want to eventually say to her IF you do say it in a very convincing manner. the more confident you will be the more subdued she will react.
