A constant irritant for you, isn't it?
it is far worse and horrid than I can capture in only 140 characters. The principal at my school has shown her true racial prejudice with her latest stunt.
That's not good. Have you contacted anyone who can help lodge a formal complaint? (you might want to record her saying this stuff-phone in shirt pocket)
Sounds like the change should be with thte principal, it would be a big loss to the students and staff to lose your knowledge and skills. Good luck!
