Akshay Khanna as Sid was complling, lwas unable to decipher the nuances during my first encounter with Sid's character. Looking on the illustrations colored by Sid, you could tell how perplexed his character is.
"Darwaza Khula Nahi Hai, Andar Koi Aa Nahi Sakta." None could infiltrate and sabotage the harmony he has inside coz he never lets them to do so. He thinks he is vulnerable, concerns about the ramifications, if he disentangles the doorways "something unbearable might happen?".
"Bakse ko Kaske Bandha hai, Koi Chori Nahi Kar Sakta." Sid cherishes his dreams and looks forward to them being pursued by him. He is fragile, indeed. 'Baksa' is like his heart, and he has enclosed his dreams inside that box, fearing by any chance they might get shattered or torn apart.
You can call me drunk or stupid enough to be, the way I have deconstructed Siddarth's character in a way that likely to appear mediocre or mundane. Sid easily gets offended, he is self-absorbed, he doesn't seem to be living his life to the fullest and lastly he doesn't tend to hear anything terrible about his loved-one's. Sid is you, me and every one of us. He is us. Do watch the film 'Dil Chahta Hai' and get enchanted by his character.
