I'm still wondering why my college groupmates chose to present a last-minute piece when we'd already put together a much better presentation.
What everyone normally did was they each completed a part of the project, then clumsily welded the pieces together. What I did was apply some division of labor. Someone did the research, I did the writing, and the other two were supposed to present the thing in front of class. I sat in my chair expecting them to do their part.
Disaster! They presented something completely off-script. I tried to explain things to the teacher and my groupmates actually barred my way. I twisted someone's arm and caught up with the teacher, but she wouldn't accept my explanation.
I still don't know why my groupmates had that brainfart.
