Can you guess which one is my mother?

Happy Halloween!  This is my mother and her great group at Sunnyside High.  They are a hip group!  Always having parties and rallying together for a new ways to keep the spirit alive in their administrative office!  I owe it to my mother who always taught me to make the best of things, make Good Memories, and  Have Fun!  Anyway, there is never a dull moment here, you can tell!  I suppose I get my spirit from my mother!  Sorry mom, I don't know what you are?  Cheeta girl?  Cave woman?  Wilma Flinstone?  I don't know.  Hmmm.
