“Human: That's stupid. Isn't there grass on both sides?”
“Grass isn't greener on the other side of the fence ... it's just a different kind of grass.”
“It's not that the grass is greener on the other side, it's that you can never be on both sides of the lawn at the same time.”
“The grass isn't always greener on the other side it's greener where you water it”
“The grass on the other side of the hill may well be greener, but you should always check that there isn't something with teeth and claws crouching in it.”
“A man must be both stupid and uncharitable who believes there is no virtue or truth but on his own side.”
