Buttonwood tree doesn't need leaves to tell us the importance of love, but it may not be as tough and lasting as we think. This revelation comes from a text called "Flying Butterflies Leaves". The article tells us that when the plane tree is flying, we get to know each other, but in another season when the plane tree leaves are dying, you stay away from me. This artistic conception implies the decline and end of love, and also reminds us to face the cruelty of reality. On the other hand, it also implies that love is short-lived, just like a fairy tale, and may be an elf driven away by the real society.
However, even in the face of such enlightenment, our hearts still have a deep desire and expectation for love. This is also the embodiment of the complexity and richness of human emotions. We may get hurt in love, but we will still bravely love, expect and pursue that deep emotion. This is the philosophy of life revealed by buttonwood.
