After five or six years of life, I reached the age of 20. I have experienced so-called love, family affection, and friendship. To me, these three emotions are very different. Love, from desperate pursuit to gradual rejection. Family love, from closeness to intimacy, gradually develops. Friendship, from blindly demanding to learning to be tolerant. I have learned a lot, I may be very old at heart, but I seem to be getting more and more confident.
