To elaborate on your point, it is important to remember that the problem of onas devarim not only manifests itself in schools, where teenagers and children bully others, but also in our homes, where we all fail at times by hurting our children, spouses and siblings through acts of onas devorim. If we all take a step back and learn from you and your rosh yeshiva, we will be able to work on stopping the hurt we cause our children, spouses, parents, and siblings.
Once again, I appreciate your special letter and hope it will highlight to our community the sensitive issues that you raised, along with the important lessons of onas devarim. Hatzlachah in raising your special family!
