Hi, ***,
Today, I'm here to present a TV commercial which touches me deeply. It is not a traditional TV commercial, it's a public service ad. This ad is about a father, who is an old man suffering from Alzheimer's disease. The only thing that he remembers is that his son likes eating dumplings. During the holidays, the son comes back home to visit. The family gather together for dinner. Half way through dinner, the old man starts packing the dumplings into his pocket. The son finds it strange and asks, "Dad, what are you doing?" The old man replies, "My son likes dumplings, I'll bring him back some." This ad is not about selling, but sending a message to advocate the greatness of parental love, which is so unconditional. This kind of love is thicker than blood, and it is not going to fade away, no matter the distance and time. This ad also reminds me of the tender, love and care extended to me by my family. All at a sudden, it dawns on me. From now on, I'll have to cherish every moments with my family. For they may turn grey, get sick or even pass away one day, before I have the chance to show them my love.
