‘Departure is painful’. So is the departure of the trees painful for the poetess. What will happen after their departure?

Just like the departure of someone close to us is painful, so also is the departure of a tree. When they are planted as a sapling they look nice and enhance the beauty of our surroundings. But as they grow and spread out their branches, they look wild and require mor space for their growth. The roots create cracks in the floor and the leaves stretch out as if to move towards the glass, perhaps in need of sunlight. the soft twigs become strong and stiff. So the trees breathe and they are welcomed by the wind. The moon resembles a broken mirror, reflecting off the leaves. The poetess reveals that she will feel lonely after the trees departure.
