what is the single major memory that comes to the poet on a rainy day.

The single major memory that comes to the poet on a rainy day is the memory of his mother. The poet recalls how his mother used to look at him and his siblings affectionately, especially on rainy nights when she would put them to bed. This memory is the emotional core of the poem and brings a deep sense of nostalgia and comfort to the poet amid the rain. The sound of the rain acting on the roof triggers a flood of these cherished memories and feelings, making the rain a source of bliss for the poet as it carries him back to those moments with his mother. The poet's mother and her loving presence are the significant images that come alive in his mind while listening to the rain, evoking feelings of warmth, safety, and sweet recollections from childhood. This memory is described as both a comforting recollection and a poignant reminder of loss, as the mother is no longer alive, but her memory remains vividly alive in the poet's heart during rainy days. Thus, the rain becomes a catalyst for the poet's memories, especially of his mother, filling him with a blend of happiness, longing, and hope.
