Why does the Torah tell us when Miriam's punishment took place?
Wouldn't it have sufficed to just remind the Yidden of the punishment alone?

The Chofetz Chaim was once travelling in a train. He watched a woman get up and open the window near her seat. A minute later the woman's daughter got up to close the window. The woman got up again to open it, and her daughter came shortly thereafter to close it.
