I had another go at the “Where the sidewalk ends” interpretation …

There is a place where the sidewalk ends,
the meadow spreads, and garden begins.
And there the dunnock bops her head,
And there the rhubarb bursts his bed,
And there the fox sniffs around the shed,
to hunt a mouse or two.

Let us leave this place where the cars honk loudly,
And the sea of people shove us stoutly.
Let’s rest where the birch stands proudly,
Where we dance and sing and snooze,
Walk slow, run fast, jump high without shoes,
In that place where the sidewalk ends.

We will snooze in the sun with Mr Fox,
And cuddle neighbour’s cat who wears white socks.
And read a book, and give you a hug,
And be as happy as a bug in a rug.
