The title "A Sunny Morning" is justifiable in the context of the play in a number of ways.

First, the setting of the play is a park in Madrid on a sunny morning in autumn. This bright and cheerful setting is in contrast to the gloomy and rainy weather that is often associated with autumn, and adds to the overall lighthearted and positive atmosphere of the play.

Second, the sunny morning serves as a metaphor for the renewed relationship between Dona Laura and Don Gonzalo. The bright and cheerful setting represents the renewal and rejuvenation of their relationship after many years of separation. Just as the sun brings warmth and light to the morning, the characters' reunion brings new life and hope to their relationship.

Finally, the sunny morning reflects the positive and optimistic outlook of the characters. Despite their age and the challenges that they have faced in their lives, both Dona Laura and Don Gonzalo are optimistic and take joy in the simple pleasures of life, such as feeding the birds and reading poetry. The sunny morning serves as a symbol of their positive outlook and their ability to find joy and meaning in the present moment.

Overall, the title "A Sunny Morning" is justifiable because it reflects the setting, the themes, and the characters of the play, and captures the positive and optimistic tone of the story.
