When approaching a woman within a group of women…

…do you include the entire group in the approach? Usually out of friendliness when I approach a woman within a group, I’ll ask the entire group a question about how they’re doing, or what brings them out, and more often than not, the girl I wanted to talk to in the group ends up not conversating after the second or third exchange and I’m left talking to the fattie of the group.

Should I change my approach and focus on on the one I want from the beginning? Rather than including the whole group?
