The theme of William Shakespeare's Sonnet 73 is the importance of the friend of the poet's loving him more strongly because of the temporal state of life. Calling attention to his aging in order to convince his lover of the urgency of full affection, the poet uses images such as "yellow leaves" and "twilight."
