complaint

on last friday 15-06-2012
have group work with assignment, i though my group mate will do some efficiency work to me
but this is the dream that cannot be done,
the result is they spend 2.15 hours, they just do 1.5 hours work to me,
and one of them are not doing work at all.
i wanted start to complaint them, but i din do that, as i always tell myself no people can be perfect
when i start to discuss with them another assignment, they make a joke said that they want to get or hired people to do that assignment, i eventually very shock, when he saying that,
feel want to ask them a question, "Why are you studying at here ?Since you would like hired or get help from others to finish your task"

i just can tell my own i am unlucky this time
