Haven't you noticed

In the previous, chapter we read that after Rashid and Kamran came back from the police station Rashid got busy with his work and Salman came to Kamran and said some strange things to him that Rashid's friend would never say, like:

Salman: Look I am Rashid's friend and I am not saying that he is wrong but don't you think that since you have joined the gang you have stopped thinking by yourself You only think and say what Rashid makes you to

Kamran: What do you mean?

Salman: For example about Kashif. Haven't you noticed, You used to live peacefully and happily with him until Rashid came right?

Kamran: You are right! I haven't thought about it before but this doesn't make him innocent

Salman: I used to think you were a piece of mind but I was wrong You only think by other people's mind. Look! Before Rashid came what you used to think about him?
