What is the meaning of the saying the grass aint greener on the other side?
It's Fairly Simple,
Just because you may think things look better over there, or a person must be doing well, you might be wrong and things are not that good over there or well with the other person. what you see is not always real. Shows on TV or the movies always look better (greener) than in real life.
