Context :

My informant is an adult male who was born in the Gangwon Area of Korea, which is located on the East side of the peninsula. He received Korean education throughout his life and he now works in Korea. Here, he is describing a commonly used proverb that is used in the Korean society. He is identified as S in the dialogue. This piece was collected over a phone call in Korean and was translated into English. 

S : This is a pretty common one too. I don’t think this only pertains to the Korean society but it is true that you need to be aware of what you say no matter what. If you are gossiping about someone in public, actually, even in private, you never know who will be listening to you and spread the word. It’s kinda sad because it seems like it’s trying to tell us that there is no one to trust in this world but also tells us that you, yourself, need to shut your mouth and don’t make unnecessary comments about others and mind your own business. 

Analysis :

This proverb was very interesting because of the animals who will be listening to the person talking. We can also learn that a lot of Korean proverbs have animals taking action. By introducing the bird and the mouse as listeners, it makes the audience imagine birds flying around and mice running around to spread the message of the gossip. Upon my research, I also found a very interesting article that was published by JoongAng Ilbo in 2010, that shows a possible scientific explanation to this. This article talked about the movement of the sound; sound moves from cold places to hotter places due to refraction and during the day, the sound moves from the ground to the sky due to the sunlight and its heat. On the other hand, during the night, the air cools down as the sun sets and the ground is comparatively warmer because of the lingering heat inside the soil. Thus, during the day, the birds are more likely to hear what someone is saying because they are in the sky, and during the night, the mice are more likely to listen to what someone is saying. Before this project, I just thought this proverb was only meant to give a lesson to be aware of what you say to others. However, learning a scientific background made this quote more interesting and I wonder if any more proverbs have a scientific explanation to it too.
