I remember seeing those kind of sweater vests with the emblems on girls here in WA but for the life of me I can't remember what girls club they belonged to. I keep thinking Glee Club, but not sure.
I just happened to really notice that strange arm stretching from the second girl back row, right, across the third girl back row. And also I noticed before how Stanley Ann doesn't fit in with this group.
We don’t know how many girls forgot their sweater or were looking elsewhere because we aren’t seeing the entire picture. You can see another person who’s cut off on the bottom right row and another person to the right of SAD. Also, notice that IF there were just 8 girls in that picture that 4 would be facing left and 4 would be facing right but that’s not the case here. We have 2 facing left and 6 facing right so there are several missing girls who have been cropped out.
With the arm, the “mom” girl beside SAD, you can’t really tell how bent her arm is. No, that’s not her arm stretching all the way to the second girl. That arm belongs to the secon girl. “Mom’s” arm his hidden behind the girl in front of her, but it doesn’t look to be the same bend as the others. Her elbow bend angle is between the other’s and SAD’s.
