Problems in an association can not be avoided. Between friends with each other would happen friction. But that's the spice that is making life more rich in ice cream.
How do we respond to one's character? Here we need to concern with things like that. What is it like? If I'm like this how? Do I have to do this? It is about how we can keep each other's feelings. Maybe there are friends who are sensitive, irritable, always happy and others. Of course we have to distinguish all that.
Here I am not talking to discriminate friends, but different in addressing. For example joking with a sensitive person with a person who is not, would not it? Because of this difference we should not speak.
