Question

What does ranga mean when he say "how can i marry a girl with milk stains on one side of her face and wetness on the other"

Answer 1

This expression reflects Ranga's views about girls. He considers all girls immature. He feels almost all the girls in his time were immature. He cites the example of an officer whose twenty-five year old wife had not learned to talk lovingly. So Ranga thought if the girl he married might also turn out to be immature. She might mistake his words spoken in love as words spoken in anger.

So Ranga not only wanted to marry a mature girl, but also the girl he admired. For these reasons he used the expression "how can i marry a girl with milk stains on one side of her face and wetness on the other"
