When a new born child is black in color there is dependency in the family. Then some old woman says "Parudi. Nammatthu Komu paattiye mari irukka. Komu Patti rajatthi mari Iruntha. Ivalum appati iruppal." Standard solace from older and wiser people. Everyone has some relations who look more Dravidian than most of the non Brahmins.
