my experience of doing role play

My role play is very said to talk.Many thing happen.I regret because choose wrong person to be my group.My group not doing the prepairation for the presenttaion.Because everybody sellfish.Their just think about their problem and always given excuse.So at the day presenttaion we all do the role play with unhappy feeling.My role play is no doing right.the conclusion,my role play is "suck".
