These children are compared to rootless weeds. Because weeds are some unwanted wild plants grown in our paddy fields. These weeds are called rootless because they are not welcomed by us. They don’t belong to the paddy fields which we grow. So, we try to pluck them out. These children of slum are also like these weeds,unwelcomed and unwanted by the rich world outside their slum. They are pale because of malnutrition and unhealthy life style. The poet perfectly compares the insecure life of the weeds to the insecure life of the slum children.
Their face is unkempt and dirty. Their hair is untidily scattered around their pale faces. Pale face represents both unhealthy life style and hopelessness.
