In your way u r absolutlely right even today marriages are happening at v young age n both girls n boys learn to adjust . and yes pros n cons are there alright but these days don't girls want career go for higher studies may be join some professional courses none of the parents of Meethi tried to talk to her out of it or about it they did not even batted eyelids at the shock Rathor and Mukta gave ...like I told before marriage is for life time and if u marry a wrong person then the entire family ad relatives suffer that is what is gonna happen
personally I feel 18 or 19 girls are still kids and immature to handle all the responsibilities that comes with marriage that also depends what sort of in laws she gets today girls need to stand on their own feet and know how to earn money you never know what might happen tomorrow...and after marriages how supportive your in laws are when it comes to your studies and how they treat you depends afte all young age does not come back and walkng step by step in life is better A matured girl knows how to handle situations and how to handle relatives also
