"Rely on your parents at home and rely on your friends when you go out." This sentence illustrates the importance of friends, and also explains that the role of friends lies in reliance, and more importantly, mutual reliance. It is not the kind of behavior that blooms flowers of evil in the name of friends and watered by friendship for personal gain. The difference between the former and the latter is that: the former relies on each other and helps each other, especially when friends are in trouble, they rely on each other, encourage each other, and help each other to get out of trouble; while the latter "waters" friendship when friends are happy; when friends are in trouble, It is wise to protect oneself and abandon it, and what is worse is to add insult to injury and add insult to injury. 2. "A friend in need is a friend, and a fire is gold." This is what we ask of our friends, and it is also a criterion for judging the authenticity of friendship; it also shows that friendship needs to be refined and sublimated. The friendship that calls you brothers at the wine table and supports you when things are going well is not true friendship; but the friendship that gives you words of concern when you are proud and gives you sincere words of concern when you are down is true friendship. Because not only is it not flattered by the temptation of fame and fortune, but it is also verified and sublimated in difficulties.
