This government resource is managed by DHHS and contains a wealth of information for schools, parents and students to help curb bullying.
I like it.
Regarding the Golden Rule Pledge and the Days of Dialogue and Silence, I only know of one district where they may be observed together. All around, this year seems more quiet than any previous year.
Instead of a walk-out, I advise a walk-in. Kids, walk in school and promise to treat others the way you want to be treated. Not only is that educationally sound, it sounds like a pretty good moral philosophy.
