In the last few days I have seen three interviews. Pooja who said the one thing she would change about Parth is his inability to talk to people. Shubaavi's article today says that while she immediately bonded with Pooja, Erica, Swahil and Udaysir, it took her longer with Parth. And finally Parth himself said that he was really shy on the Christmas party day.
He also mentioned in the interview that on the night he went out with Pooja and Saahil he was in a bad place and really low.
It must be so hard for someone like Parth who is shy and probably going trough stuff in his personal life to put on a smiley face always for their work and their fans!
