The greener grass in my friend's garden

I love my garden
Lush green grass, bright red roses and the smell of the wet earth
But something seems amiss

I don't know what
I mow the lawn, water the plants, trim the flowers, sit back and look at it once again
But I am not happy

I turn to see my friend's garden
Kids playing in her lawn, a bird chirping on the fence, butterflies fluttering from flower to flower
I wonder what is so good

I stand on my toes to peep over the wall
The lawn mower stands broken, the garden hose lies unused, pliers are rusted
But the grass in my friends garden seems greener than mine
