My beloved grandpa has passed away for several years. I suffered from my naughtiness every time I thought of him. It was a summer day, hot and stuffy. My grandpa was seriously ill. Mom bought a watermelon for him. But I was so naughty at that time that I wanted to eat it alone. Mom beat me for that. But grandpa said to her, "Let him eat. Anyway, I'm dying!" I saw mom sobbing. Then my grandpa died after a couple of days. I am so regretful that I can never forgive myself. I made up my mind to be a good boy.
