Why is Gaurav so grumpy?

After his disagreement with pre-teen Sarthak which eventually led to Sarthak walking out of the house, Gaurav is yet again at loggerheads with one of his 'children' in NDTV Imagine's Pati Patni aur Woh. This time it is him and his teen Aditya who strongly disapprove of each other.

According to our source, "When Gaurav and Mouni had gone out on a romantic dinner date, their teenage kid Aditya started rummaging through Gaurav's closet apparently checking if any of his attires matched his size! When Gaurav and Mouni return home they are utterly horrified at the kid having behaved like a burglar!"

Adds the source, "Gaurav repeatedly tries to set boundaries for Aditya to make sure that Aditya realizes, the master bedroom belongs to him and Mouni and that he is to stay away from there. But like any teen kid, for Aditya any rule has a loose end. On the other hand Aditya tries to negotiate on his pocket money and night deadlines expresses the fact that he is not happy with Gaurav's "Hitler" like tendency of imposing rules and limitations on him."
 
The fact that Gaurav and Aditya are not very fond of each other is evident from their behavior. Is Gaurav's arrogance surfacing from the reason that he's feeling insecure as Aditya is not much older than Mouni?
