The role-play

LAst week, my English lecturer says that we will be having an role-play

When thinking about this, I really don't know what to do. There are two girls and 1 guy in my group. they say any title will does as that day my class will ends until very late ....

When talking, they A says 'never mind, anything also can', B says ( I want title related to LOVE) and Lastlly,C(the only guy) says that 'cincai'

But the problem is, when I told them some stories, they banned it. I'm so furious now about the role-play by the two-headed snake.

Please if u really wan 2 banned my idea, can u pls tell me the reason.....
Now I had my decision, don't they ever think about asking the ideas from me..... my idea stuck already because of that three DEVIL....Luckily the lecturer says can chooses the title that written by her.....
So, I don't care anymore, I only have toprepare my part, theirs-except I die....
