Regardless of how much the Bigg Boss house bickered, fought and made it nasty when there came distressing situations for any of them, they all pitched in for help and remedy. Well, almost. Bharani was one contestant with whom no one seemed to try. But it was an early time in the show, so probably this can be understood.
But as the show progressed, the contestants often found it really difficult and had it not been for the others to reach out and comfort them, they could not have continued on the show. Kamal Haasan even praised Snehan, especially for this aspect. Snehan and Vaiyapuri were two people who did this repeatedly, which added to their support and goodwill.
Lesson: Those of us blessed with families and/or friends must treasure them and be there for them regardless of any conflict.
