Actually thats really not how their family functions, yes shaura is wrong in his approach, but he also has a point right now tenth standard is more important than his love of cooknig, and if it was just only mom and dad than what about the million times rj has ''interferred'' in anshus life?
in joint family you dont see that only mom and dad can say , the age gap btw shaura and anshu is such that he feels very fatherly and elderly towards hin so he says what is best for him,even when he wanted to work his family was that you will work for somepone when you have a bussiness? that doesnt mean that ppl who work are lesser it is just that for thme it meant more for him to do busisness. he is thinking along the same lines, and though his thing that cooking is a waste of time is a good track as it will show that all have to accept the kids true profession but i still belive that anshu needs to focus on studeis and maybe after 12th og to a culinary school, but till then he needs to piroritize studies.
at this age you have phases , some day you want to be a cherf, astronot, doctor, let them pursue it but it is the duty of elders to keep them focussed during this phases to one constant and that is studies.
shuray is right in a way but needs to tone down his dicatorail attitude.
