What are the classic sentences that hide love deeply?

1. You are young when you have faith, and you are old when you are doubtful; you are young when you are confident, and old when you are afraid; you are young when you have hope, and you are old when you are desperate; time makes your skin wrinkle, but you lose it. Enthusiasm damages the soul. ——Carnegie

2. There is only so much warmth in my life, and I gave it all to you. But you left me, and you told me how to smile at others again.

3. When summer comes, I realize that "Wherever it's cool, stay there" is really not a curse word. It is definitely the most sincere concern and the deepest love.

4. Do you know that I have spent hundreds of years of loneliness guarding you alone, and that I have sung my love songs for thousands of nights only for you.

5. Let those who never wake up fend for themselves. If they complain, we plug their ears. Because they are unwilling to have any gratitude for life, the world, and life.
