On Children's Day we headed over to Gwacheon with friends to spend some time at the park. They have these statues there which tell an old Korean children's story.
Apparently there was a really lazy boy who somehow ended up putting on a cow mask. Unfortunately, he then turned into a cow and had to work the fields. Finally, he got restored to his original human condition and decided he wouldn't be lazy anymore.
I'm sure I missed some important details, but this is the main gist of the story.
