opw work

I had my first OPW project work yesterday and I was nervous about it as it was my first time having this work with a bonus percentage if the project grade was an A. I grouped up with Jun Hui, a quiet and shy person, Aloysius, an independent and introvert person, Mick, a serious person with a strict "no no" attitude and last of all, Han Wei, one who likes to clown around and fond of contradicting others. Well, with Han Wei and Mick around, the natural enemies never get along well with each other and they always end up in an argument. Mick never seem to be fond of Han Wei's actions. Both of them never appreciate the affinity shared between us to be classmates and caused unity between the team to be broken. Mick was probably frustrated about Han Wei's actions and his personalities. The quarrel began at the first discussion but we managed to stop them , however, it took a turn for the worst at the later discussions especially when Han Wei ignored Mick's speech which result in another round of words. We tried to prevent the bitter argument but to no avail. We had no choice but to separate the two and to talk some sense into them and asked them to put aside their feud and to contribute to the project. To our relief, it managed to work and they were more united in the team. I cannot seem to comprehend on why they cannot admit their own faults and forgive the other party. If you have any ideas, could you tell me?
