A lawn mower in the distance.
The smell of new mown grass.
The drone of the bumble bees checking out new places for a nest.
Birds singing with their musical notes in a language only they understand.
The tinkling of the windchime in the breeze drifting across the porch.
Children laughing and playing.
The gentle purr of the cat as she sleeps on the sofa.
The sighs of two contented dogs dreaming of chasing rabbits.
The chattering of the squirrels in the trees.
All these things play through my mind and I gently drop off into sleep.
