“At night,” why at night? Because sound travels only at night, that is why it is stated: “At night.” Rabbi Aivu said: Night draws lamentation with it.80When one cries at night, it has a greater impact on those who hear it, and they are moved to cry as well. There was an incident involving a certain woman who was in Rabban Gamliel’s neighborhood. She had a young son and he died. She would weep over him at night. Rabban Gamliel would hear her voice and recall the destruction of the Temple. He wept with her until his eyelashes fell out. When his disciples sensed it, they arose and evacuated her from his neighborhood.
