hey prem diwani,i am not pointing out that you are wrong.. just writing down what I feel about it...okay?
The night when Megha got the diary was a very emotionally hectic day with revelations about Amar,about what Mohan did,Mohan leaving the mohalla, she trying to stop him, the botheration caused by his HAQ wala questions,Mohan coming back and her ambivalent feelings about it, knowledge about nanhi's kidnap,MG coming for dinner, how he openly offered her the red rose right behind papaji's back, finally just glancing through the diary...it was a roller coaster day...and i feel the CV's did the right thing by not showing her reading the diary then..coming to the next day,at a time when she was expected to be having FB of Amar , she caught herself having FB of Mohan...she was totally confused and wanted to be alone with her thoughts .. hence she ran away to the park..to do what she and Amar used to do together, feed the pigeons...And that night , obviously she was not in a fit state of mind to even think of the diary..again realistic...
Next day morning when she went to papaji's room to light the diya, she did see the diary and sat down and glanced through the pages...but before she could read in earnest or think of taking the diary to her room, MIL called her.. And she kept the diary there and went to the hall...Then she had to hurry to meet Indu... By the time she would have come back the other members of Vyas family would have already finished reading it.. But why they did not tell her ...? that is your question.. Well,this is not something which you can reveal when somebody is in a hurry to leave for work... And they must have planned to give it to her once she comes back from work, when she can sit peacefully in her room and read it... Another thing, they themselves needed time to digest the facts of the letter and discuss about it.. It is such a delicate issue...So I feel the CV's handled that quite well.. of course they could have shown some more episodes of MM scenes in the office before embarking on this accident plan.Well,...I hope that they are planning for really imp ,long and much more interesting tracks... hence they rushed through these..I like to think like that... I want to keep my faith in the CV's intact
