Search Results: shy girls making her talk

So I have a project with these four people, two girls and two guys (one of the guys often gets angry for no reason.) I had another group I wanted to work with, but my teacher thought it was unfair for all the unskilled students if all the skilled students were in one group together. So the project is to make a 15 page children's book and I was in charge if making characters and the other girl said she was going to help, while the two boys agreed to make the story, and the other girl was going to help as well, then revise it later. However, they haven't helped me at all and the project is due a few days from now (not the book, just the storyline, character development, revisions, and cover). The girl who said she was going to help me didn't even do anything at all either. I'm still working in the characters, the storyline (which the two guys were suppose to handle), and the cover of the book. I even gave some general information and told them some ideas of mines so they could create a storyline off of the information they had, but they continue to talk to each other while I sit off to the side picking up their slack. The only idea I got from them was from the girl saying we should make it like Rhythn Thief (because no one's helping me, I switched directions of the story). I think of saying something to them, but I'm really shy and I usually keep the myself, and since the guy with anger problems for mad before at someone he makes me a bit nervous. Actually, people who talk a lot in general make me nervous. But I was also thinking of asking the teacher to not give them credit because she already talked to them once about contributing to the group, but I'd feel like I was telling on them. What exactly would you do if you were in a situation like this?
