Students asking about Shahrukh Salman spat

Lately it was known that Aamir Khan was troubled by the questions asked to him by some 9th standard students. All the kids were asking him about Shahrukh-Salman spat that happened during Katrina Kaif's birthday party.
Reportedly, n Friday, Aamir was at child artiste Darsheel Safary's school Green Lawn at Warden Road to launch the DVD of Taare Zameen Par by the hands of the school's principal. Darsheel's classmates too were present there. Aamir arrived at Green Lawn School at 11 am and left by 2 pm.
Aamir decided to take a tour through the school visiting all the other classrooms right from the primary section to the 10th standard after the DVD launch. He went to each classroom, swapped small talks and interacted with all the students. Aamir also gifted special notebooks to almost 1600 students.
Then when he was visiting class 9 students, some class nine students stopped Aamir. They stopped him when he was about to leave their classroom and said that they would like to speak to him. After talking to him for a few minutes they suddenly launched the attack, asking Aamir about the details of the fight that took place between Shahrukh and Salman Khan during Katrina's birthday party since he too was present there.

Aamir was astounded, as he did not expect a question like that to come from students. Initially, he had no words to say. But he soon collected his intellect about him and geared up to answer them.
He explained to the students that when two friends fight over an issue, the third friend should not get involved. It is the best to leave the two friends to resolve their differences themselves. The children seemed to be happy with Aamir's answer.
But the question still persists. What was the spat all about?
