Unseen Letter

Since I was little, I often heard stories from my grandfather that had a profound impact on my memory because when I was a teenager, my grandfather suffered a stroke that left him unable to speak. Because I was studying abroad, my grandfather and I were separated by miles. The stories my grandfather told me left a lasting impression on me, and I always remember them because I miss him and want to fulfil my promise to him, which makes me long to return home.
