What can I do? That is a question that we have heard time and again this summer. One small suggestion: write a note of condolence to the Dallas or Baton Rouge Police Departments or the Castile and Sterling families. We will collect these notes from the Chizuk Amuno community and mail them on behalf of the congregation. Rav Huna, the Talmudic sage, suggested that when one is ailing, sympathy often helps more than other remedies. Handwritten notes may be dropped off or scanned and emailed to me via dwechsler at chizukamuno dot org.
