In the familiarity of our relationship with our parents, we often overlook the gradual appearance of wrinkles and grey hair on their bodies. In childhood, we always long to grow up quickly, but when we do grow up, we realize that the price of this process is the aging of our parents. The grey hair and fine wrinkles of my parents have become tangible evidence of my growing-up years. Every time I see them aging, a sense of powerlessness over the passage of time wells up in my heart, prompting me to reflect on the fragility and preciousness of life.
