The grass is always greener at the other side.

Nah... just saying the thoughts on people's mind.

Grass is always greener at the other side.

You cross over, you can either look at the grass and leave, or take a bite of the grass.

The possible result for taking a look : your heavy body left footsteps on the grass. The grass which you have stepped on will either grow to be prettier because of the movement of the soil OR die on the spot.

The possible result for taking a bite : you grow fatter and healthier OR you got poisoned and mampus.
