I think you are all crazy assigning these adult-like personas and expectations of kindegarteners.
The kindegarteners aren’t racially profiling each other and kicking the boy in the crotch is not wise advice.
Just tell her to ignore the brats, go find the nice kids and play with them. It isn’t that difficult, really.
As for yourself, FLU – do the same with the parents. Don’t focus on all the Carmel Valley social posturing. Just find some nice people and conect with them. I guarantee you they are there.
