The deep end

In the shallows they splash
With weak-muscled panache,
While their mothers watch well
Lest they do something rash,
Like ride on a swell
To the deep end.

Yes the water is cool
In this uncovered pool
And the markings are clear,
So only a fool
Would venture too near
To the deep end.

Step by step, as they grow,
Straining down with one toe,
Till they’re steady of limb
In the unending flow,
Till they’re ready to swim
To the deep end.
