There is a touch of sadness with every goodbyes in life, and sometimes we feel thankful with tears in our eyes. This commercial is almost like writing a farewell letter to a good old friend. We took an approach to bring a lite smile from a moment of sorrow, simple and slow piano melodies did a good job delivering that. What plays a significant touch of saying “Goodbye” is the airy sound that breezes through the end, like a gust of wind passing through, going far and out of reach.
