Cannot fully blame Suman for behaving like this. Her father asked her what she was feeling just for formality. He had already decided her life's future course. Many Indian parents commit this mistake.
Instead of showing off that they are elders and hence know everything, once their child is grownup they should be treated like that. Don't be a friend, remain a parent but do not treat them as toddlers.
Now if only her dad would have sat with her alone and listened to her, then would have told her why he thinks the way he does, instead of announcing his decision things could be different. Suman never said that now she doesn't want to join the army. Love can be a great motivator but many parents fail to see this.
This is a country where young lovers are killed just bcoz they don't let parents decide the life partner. I hope they show both dads regret what they did bcoz ultimately they will show Sumo regret.
Also, there is high tension at the LAC right now, so I hope they show Sumo's dad getting posted there and then the devastating news. Maybe that'll make Indians see where the real news is instead of the circus going on in the news channels.
