Here's one that may work for you
Step-by-step explanation:
Shining white foam in the blazing sun
I wondered over all day
and it came crashing by anon
until I went my way.
And it does the same when I am not around
The ocean won't stand still
The sands never could throw abound
Ocean's soft seeping shrills.
But trapped in seashells take away
the remnants of this water too
We are here to hold the sway
over what nature can do
In seashells i took home i only found
the sounds but not the soul of ocean bound.
