Human, complicated

Finally new semester starts
as usual, we have to  divide into groups for assignment purpose
working in a group is not easy
because different people has different opinion or thoughts
most of the people will stick to their group of people
with their own friends only
for those who always alone or small group of people
they have to join others group
sometime stick to own group doesn't mean can work very well with each other
human needs communication very very much
if the group member does not communicate with each other
then a lots of problem will appear
sometime may cause misunderstanding between people too
human is so complicated
because we have different identities play different characters
