What do You Call Worth?

People have always been saying "be wise."
How do you think of the being-wise thing to be on earth
when it gets to the point of friendship?
To be a friend, should we give up or back up when friends get faults?
Every men has his faults.
When you find friends hard to get along with in some ways
, especially in ways you can't stand the most
, is it right to let go of the friendship?
Or should you back him up and encourage him
even you know that is who he is?

A tricky problem!

There were problems between my roommates for a long time.
It is difficult to solve.
Therefore we live in an apparently harmonious atmosphere
which breaks out to be a cold war suddenly before your notice.
We still need to learn from the people, the society and the world.
Tolerance could be the greatest antifriction for conflicts and complaints.
Being irritable won't be welcome to everyone, so does being bossy.
What kind of friends do you think is worth having?
