I really feel bad for Sid, coz no matter what Asim keeps owning Sid.
Phele supposedly Asim used to poke him. Chalo ye sahi bhi hai, but that's the name of the game. Like I have repeatedly said, BB is all about action and reaction and how one handles all this. It's a mental game. So Asim's slightest poking would trigger Sid n he would give a much more aggressive and strong reaction to the poke, which proved that he was mentally weak.
The other side, Sid too constantly pokes Asim, but Asim plays it cool. This leads Sid to stoop lower and lower to get a reaction out of Asim and Sid ends up looking horrid and a bully. This proves Asim is mentally strong.
So in both the scenarios Asim emerges the victor. Poor Sid, doesn't know how to counter asim. I'm sure in that therapy session with BB, BB must have conveyed to him how bad he looks abusing Asim's family. But Sid can't help himself...that's how he is naturally.
