Without sincere friendship, relationships are very unstable. For example, a friend who approaches you with interests as the guide runs faster than anything when you have an accident.
Although it is said that many times, even if you give your heart, you will eventually be betrayed, but I think such people are still in the minority. Even if there is the possibility of betrayal, we still have to show our sincerity before we can get another sincerity.
No matter in college or in your long life before or after, friends you make may become a part of your supporting force on the road of life.
