Who wouldn't get irritated and angry over small issues in such conditions?
The fact that he loves Praneet (he voted to save him this week) shows he probably only took his anger out on him out of understanding he's close to him.. As we do with our loved ones.
People need to realise there are psychological aspects to a person contesting in a show like BB.. It's not all white and black.
And yes, he does things for "footage" - so what? He hasn't left the comfort of his own house, to sit in the background of BB like Natasa and be bored. He has to entertain himself and entertain the audience (as do they all).
I don't really make topics on IF but I couldn't stop myself today cos I don't understand why some people don't try and see a situation beyond a one dimensional way.
