When you're hungry, someone will split a steamed bun with you—that's friendship. Someone will give you the steamed bun to eat—that's love. Someone will hide the steamed bun and tell you they're hungry too—that's society. The more experiences you have, the more you'll know who can stay in your life and who can gradually drift away. You don't realize who is close or distant until things happen; you don't know who is genuine or superficial until you observe their actions.
