What does the word ‘cardboard’ denote in the poem? Why has this word been used?

Hint: The poem "A Photograph" written by Shirley Toulson connects nature's interior state to humans' current situation. The poetess narrates a snapshot of her mother's childhood in the poem.

Complete answer:
When she was younger, she went on a sea vacation with her two female relatives. Poetess also draws parallels between nature, which changes at a snail's pace, and human existence, which changes at a breakneck speed. Poetess recalls her mother laughing at the image and lamenting the loss of her childhood delights. The sea vacation, on the other hand, was her mother's past, and her mother's laugh is now the poetess's past. Both deal with their separate losses and the sorrow that comes with recalling the past at different times and with considerable effort. Moreover, the poetess is really saddened by his mother's death and feels a profound feeling of loss. Furthermore, the situation's terrible "silence" leaves her speechless.

The term "cardboard" refers to a photograph that has been pasted on a hard, thick piece of paper. This term was once used to describe a method of preserving pictures by pasting them onto cardboard and framing them with a glass front.

Note: We may learn from this poetry that we should spend as much time as possible with our loved ones before they pass away. We should take and save pictures with our loved ones. We must remember those who have passed away. We must learn to move on and accept death and life as a natural part of the cycle of existence.
