The branches of the blue gum grow for a bird, and the wings of the locust bird rest for a tree. This is a fate written in legends, but it has been acted out in the human world as a mime of speculation.
One uses poison to isolate the world, leaving only shade; the other uses migration to measure mountains and rivers, only circling around trees. They all hold the trump card of "you have to do it", but they all lose to the guess of "what if you don't need it".
Obviously the legend has proved "yes" for them, but the tree is afraid that its shade is not strong enough, and the bird is afraid that its claws are too sharp. So day after day, the wind came and went, the rain fell and stopped, and only the words "I like you" were held in my mouth from spring to winter.
Intention: You are the only forgiveness in this world for me, and you are also the weakness that I am willing to bear.
