6. Since people come to this world like ants, they suddenly get sick, gather and disperse. In just a few decades, they should be comfortable and chic, and everyone will live a full life. This is the whole meaning of survival.
7. Living alone is actually just a matter for one person. Life-oriented friends may know every mole on my body, but not necessarily my heart. Spiritual friends may know my heart, but they often brush my heart. Happiness comes, the happiest thing is yourself, and the most miserable thing is yourself.
8. However, I still make friends. The more friends, the better. Lonely souls roam in the empty sky. But the reason why people are human beings, with soul and body at the same time, can't live without friends, because when they go out, the road outside is muddy and dogs bark at the roots and walls.
