The tree tells the garden shed that it feels good to be alive on a lovely day. However, the shed responds that neither of them are truly living since they were both made, unlike animals. The tree argues that it is alive since it grows from a seed, uses sunlight and air to make food and can reproduce by making seeds of its own. The tree states that all plants are alive in this way. Though the shed says it does not want to reproduce and become unnecessary, the tree's purpose is to be part of the Earth and environment and help make everything work.
