When you give someone sunflowers, you should always give two. Because when the sun shines bright, sunflowers face the light. But when night falls, they turn to face each other, finding light in one another. So when you gift someone sunflowers, you're really saying, even in the dark, you're my light. 所以，在阳光灿烂时请尽情生长，只有这样，我们才能在黑暗时成为彼此的光。
