what does the poet say about her laughter a photograph

Dear student,
The poet is looking at a photograph of his mother with her cousins at the beach. The poet reminisces the memory of her mother looking at the picture and laughing. The poet's mother would laugh remembering the memory of the beach. The poet's memory of her mother laughing and the mother's memory are being referred to as ''wry'' and ''with laboured ease of loss''. This means that both the memories were tinged with loss because the poet had lost her mother and the mother had lost her childhood days. The laugh indicated how her mother was trying to cope up with the loss just like the poet was struggling to accept the loss of her mother.
Regards.
