There is a saying that a friend in need is a friend indeed. Therefore, a true friend is always by your side and gives you support. However, in reality, it is not easy to make friends. Usually, people with common interests and hobbies or people with the same values and judgments can easily get together and become friends. However, some people will make friends with people who are completely different from themselves because their personalities are complementary. However, for us, the problem is to distinguish between true and false friends. Therefore, if we know little about this person, it is necessary to be vigilant. Besides, in order to maintain friendship, we should tolerate the weaknesses and mistakes of others, because no one is perfect.
