Having idler in your assignment group is one of the worst thing in group task. They are just so "idle" that other team members have to cover their back. Still, that chinese girl want to complain so much. Lol. Some people just want to use the shortcuts without contributing.
There will be idler in a group, I have no problem with them, they might have their reason for being "idle". But what I can't stand is they keep on complaining while they are doing nothing.
