I was thrilled — diversity -— to have one of my sons in a school where the racial pie chart was 25% white, 25% Hispanic, 25% black, 25% Asian. But then I became very disappointed when we parents waited each day outside the classroom for the day to end. The Hispanic parents spoke Spanish to each other, the philippino parents gathered together and spoke Tagalog, the black parents found each other and preferred to chat together, and I was only able to speak with the white parents. I was ready for us all to get along, but the parents self segregated and it made me sad.
Heston said when he made Planet of the Apes, actors who played a particular type of ape all hung out together.
What you do is to stand apart from all the parental groups...eventually some of the “stand aparts” from the other groups will surface and you can form your own diverse groupings...to the shame of the others!
