Have you heard of the Sunflower Theory?

 They say 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."

Beautiful, isn't it?
