I was used to spend happy time with my grandfather, but as I grew up, I gradually started to become self-centered. Once, when I was 8, I went out shopping with him. As he and I took the wrong bus but got lost outside, I could not stay calm and shout rudely at him. I was so stubborn at a time that I wouldn’t say sorry after returning home, believing that I had done nothing wrong. I know now how ridiculous I was at that time! Yet, when I true wanted to express my regret, my grandfather had left me forever, left me with no more chances to apologize for my mistake. We are spent much time at school now, while little time is left for you to spend at home with our families. So make the most every second you still have with your loved ones, although time keeps going, waiting for no one.
