When you are in an environment (which you cannot get out of for sometime) where you are constantly ridiculed and rebuked for whatever u do or say, that's what will stay on a person's mind. Everyone has been after Gautam and are not willing to forgive him. After the mirchi incident, he did try but people didnt let go. So obviously he will be at a low because they are landing him one blow after another. If my friend were going through something like this, I would stand by that person.
It's easy for Praneet to say whatever he said because ppl are nice to him. HMs are mean towards Gauti. So obviously he's gonna rant about them. Now as a friend if you cannot even lend your ears to a friend in need, what kind of a friend are you?
