I don't get it...It just looks look a group of basic white girls
Notice the coordination with footwear as well, and you can betcha that most of them have tops on similar to the Cindy-one with the yellow top there in the middle.
As fun as it is to have interest in common with boys and just do fun crap with them, games and cars and football, having a girl friend group like that is awesome too because you can talk about all the emotional stuff that boys feel too awkward to talk about, even with each other.
And additional perk of being the only out bisexual girl in such a group is that any who're the
least bit curious come to you for experimentation. The alcohol is just an excuse.
I wonder if Cindy's friend group in the game isn't a bit similar to this. Maybe not denim freaks necessarily. ORS now needs a chain like Starbucks so we can see Cindy get a sweet cold beverage with her group.
