True friends should stand the test of time, be baptized by years and be honest with each other in the face of interests.
Friends are also a kind of fate. Maybe if one of your classmates and colleagues at school has the same interests as you, you should cherish your feelings. He or she may be your true friend.
Friends should be sincere, trust and tolerate each other.
Friends should also keep a certain distance, because distance is also a kind of respect. A gentleman's friendship is as light as water, but a friend's friendship should be light but not greasy.
A true friend will miss you when you are away, and he (she) will share your troubles. If you succeed, he (she) will bless you silently! If you fail and encounter setbacks, he or she will support you and encourage you. The person who will never leave you … is your true friend!
