In my country,there is a phrase became more and more popular called: friendships depend on wine and meat.We usually use this phrase to describe the relationships that people can enjoy relaxing things together like hanging out ,but when one faces some difficult problems the others disappear and seldom connect with him.On the other hand,some friends don't often connect with each other.but in the same case,the others will call you and help you at the first time.When you observe these people in the second case,you will find they have the same hobbies like art or music expect drinking.What they are pursuing is spiritual communication.I don't mean that hanging out is not good,I mean if you just maintain relationships with physiological ways,it is dangerous.We have heard a lot of people who divorced because of intemperance with what is called good friends.These "friends"realky like you pay them playing but no one want you to be better than them.So,what is the result like?You should improve yourself and then make the correct relationships with others.Only when you become strong, others will definitely respect you,appreciate you,even follow you.You can improve each other to be better.
