How do you say ‘the grass is always greener’ in Korean?

There are SO many idioms involving rice cakes! Rice cakes are an essential part of the food eaten here on special occasions – it’s not Chuseok Thanksgiving without songpyeon rice cakes. So when it comes to keeping up with the Jones’ or thinking that the grass is greener on the other side of the fence, it’s the neighbour’s rice cake not their grass that’s used in this idiom!

THE OTHER MAN’S RICE CAKE ALWAYS LOOKS BIGGER (남의 떡이 더 커 보인다)
