The Pun Tyrant
The expression “the grass is greener on the other side” is an ironic or even sarcastic phrase. It mocks this petty attitude of never seeing the good one has things by always looking at some way some other has it better. “The grass is greener” is something which generally doesn’t matter or may even just outright be nonsense. Hence “the grass is always greener on the other side” is neither true nor intends to be.
As for the other phrase, it’s not always true, just often true.
