Basically all these matters can be sorted with honest communication..... But yeh log khud ka dimag use nahi karte.... Mandali/ friends ka opinion pe aage badd jaate hai.....
Whatever confusion stan has about archu knowing him or whatever can be sorted if he will have a basic honest conversation with her... But he chooses to be influenced by mandali opinion on archu and her past action or whatever suits their current equation!!!!
If stan is 20, he has a long road ahead in learning basics..... All this rawas business is ok only to one section of the society.... Not overall!!!
