The biggest free riders ever!

I recently had an english class that required a group presentation of 4 and I happened to be the leader. People who know me, I am definitely not the leader type. When someone tells me what to do, I am very attentive to what they say and do EXACTLY what they tell me to do, but I'm not the sort of person who orders people around and tell them what to do.

What I've noticed with these (some) Korean kids: They are the biggest and best free riders ever. They cannot do anything that involves dividing. Maybe that's why Koreans can't dutch pay. At first it looked like everything was going fine: although there was one Chinese dude who could not speak english or korean. But then I soon realized everything was falling apart. Just because people thought that I could speak english, they came up with this weird psychology that I would do everything for the project. We were 4, actually 3 we have to exclude the dude everytime it comes to division of labor. So I divided it into 3 equal jobs and gave it to the two others. One day we gathered to show each other our work, and one did not do their work that well. I mean this guy didn't know the difference between "is" and "it". Now, the two of them were complaining that I should make the script and PPT for them. And when I said "You should write your own although I can help you with it" they got absolutely insane and mad and screamed "Then what the hell are you doing for the presentation?!?!"
It just struck me I couldn't say anything. Uh, Hello? I did my one third of share? and I even offered to help?

I'm a bad leader. a Terrible one.
So I'm sitting now on my computer making a user guide (which won't fucking print without getting the edges cut off) and an outline and finalizing a script and a powerpoint presentation all by myself and NO ONE knows that I'm doing all this. My team members? I texted them and I have no idea what they're doing. In fact I think one of them is out there partying.
