I recently changed my mother's phone and while transferring old data, I found a screenshot she had saved. It was a message I sent her after receiving my first salary 12 years ago. I had written something simple like, "Salary aa gayi, dinner meri taraf se."
I barely remembered sending it. She had kept the screenshot through multiple phones and backups. For me, that first salary was small and quickly spent. For her, it seems to have represented something much bigger.
What random things from your life have your parents preserved that you never realised mattered to them?
