fight at school

yesterday at my school, something terrible happen. My friend Ayman And Tengku  were fingting. In That time, I was chatting with Farhan and Syamil. suddenly, i heard Ayman shout with angry voices. I thought, he joking with others friend, so we let it be. after afew minutes i saw Ayman and Tengku fight each other. We saw the fighting with shocked. We do not suspect that they can fight each other, so we ran to them and break up.
 Tengku have been beaten badly. Ayman wanted to beat Tengku again but Syamil blocked him. I told Tengku to stop and asked him to return him. He follow my ordered. But went he down the stairs, Ayman follow him and talk bad to him about Justin Bieber because he know that Tengku is Justin bigger fan's, That make Tengku felt angry and get back to beat Ayman. But Ayman is 2x big than Tengku. They fight each other at the back of class.Syamil separated them again but he been beated to. So we don't have choice but to take one of them get out from there. Before we did that Syed Matin brother's take Tengku and sent him back. We calm down Ayman.
 We ask Ayman what happen until they fight. He said that Tengku make up first. He kick his leg, Ayman angry and slap tengku face. Than Tengku fight back. He also said, Tengku was angry to him before they get fight but, he didn't show it.
 After that, out of school gate, Ayman still find Tengku because he wanted to settle it today, but tengku have back.
 I fell weird why they must fight just because small thing. I have seen people fighting just because thing that they not supposed to fight. What a weird people
