"Talking about qualification Reva, you are not able to compare with Shanaya, sorry you might feel it offending, but Shanaya goes to a prestigious college, and she knows much more than you. And to be honest, I don't need to discuss anything with you, I think you need to learn some patience so from tomorrow you will go and supervise the construction site" Mahendra after this conversation refuse to talk with her. 

 Previous Reva feels too bad after listing these words, but now when Reva herself does business for years she understands, Mahendra uses the softest word to tell her the truth.

Her boss is someone who is not used to get orders and here she is ordering him. She is too lucky that her boss doesn't fire her.
