Changing seasons just isn’t going through fall to winter, into spring then summer. Changing season could also be changing the growth and development of life, like the tree here. The tree in the middle has its branches cut, and the trees to the side are green and still full of life. The green trees aren’t in the middle of changing, but the tree in the middle is, having to regrow the cut branches, which will not be the same as the way it was before, becoming something new.
