A year ago, you lent your favourite book to a friend who you thought would enjoy it. Unfortunately, your friend has forgotten to return it. The book has sentimental value to you as it had been presented by your grandmother.

Dear [Friend's Name],

I hope this letter finds you well and in good spirits.

I have been thinking about you recently and wondering how you are doing. It has been quite some time since we last caught up, and I would love to hear about what you have been up to.

I wanted to gently remind you about the book I lent you a year ago. It holds sentimental value to me as it was a gift from my grandmother, and I have been missing it dearly. I understand that it may have slipped your mind, but I would greatly appreciate it if you could return it to me at your earliest convenience.

The book carries memories of my grandmother, and its sentimental value makes it irreplaceable. I have been wanting to revisit its pages and immerse myself in the nostalgia it brings. Having it back in my possession would mean a lot to me.

I hope you understand the importance of the book to me. I look forward to hearing from you soon. Take care.
