The lesson is an informative one. It is difficult to imagine our lives without fire. Fire is one of the most important discoveries in human history. The early people of the world have used fire. So modern people started to maintain fire as a boon or friend. So we can say that it is both foe and friend. When a fire is under control, then it is a friend, and when a fire is overpowered, then it is a foe. If the fire breaks out, it can be controlled by water, sand, etc. various fire fighting instruments also help in putting out fires. If the fire goes out of control, it engulfs hectares of forests, lives, and property.
