Just like Parents try to guilt trip you while watching Baghban, You can guilt trip them by making them watch this movie.
Parents often tend to forget that their child also needs some emotional support and understanding. Instead of comparing to the other sibling, it's better if they try to understand why a child is unable to cope up with the environment or the so called competition. Instead of just blaming the child and calling them a loser, it's better if parents try to help the kid to adapt.
