human being, is that start from a word" selfish"

taking a subject called video production in this short semester,
have a group for our assignment, 5 people in a group..
one of the group member i had been same group with her before..
unluckily, her attitude on doing work still the same---selfish..
she caused a lot of trouble for me,
i try to handle it now...
unfortunately, because of what she has told me,
it make me damn depressing..
am i not a good leader..
who's problem actually?
you are always the one when didnt give opinion or any suggestion,
during meeting, u said ok..
but behind, u posted something at your facebook there,
are u showing me ur "warning" at there,
are u expect me to see it?
why dont u voice uo during meeting?
act like an adult la please...u r from 1988 de hor,
i am from 1990 de hor...
anything u not satisfy just say la...
dont always go back post at facebook as well as msn...
all of us still considering whether want kick you out from the group or not,
u still act like that,heidy, you are too selfish you know!!!!
can u dont be like that?
in the end u are the loser only,
for us, it just nothing 1 after quarreling and done the project...
for you?what u can get? have u think it?
