When Aman Mathur invites himself for dinner, Naina calls Rohit too. We see Rohit picking up a NORMAL house telephone, NOT A HANDPHONE, when he was at Geeta's house. Rohit then tells her that he was at Geeta's house. Then how did Naina know Geeta's house telephone number? How did she even know that ROHIT WAS AT GEETA'S HOUSE in the
first place? How did Naina call Rohit then?
