Agreed with Shiv's explanation - if BB wanted a "safe" task, maybe they should have included padding on the inner side of the shields and specified what is allowed and what is not. If Deepak hadn't been hurt, no one would have brought it up. Though I agree he should have apologized for hurting Deepak unintentionally and not his strategy.
And then later, him demanding Deepak apologize for his comments was brilliant I think; it made Deepak seem less like a victim. You can get away with all sorts of comments in BB but just don't hurt someone physically.
Anyhow, always dislike how housemates are so easily swayed with Salman's comments in WKW, regardless of their opinions prior.
