Water.

"My problems could swallow the ocean,
they'd go racing to the sea.

Moving with the motion,
riding the waves where they shouldn't be.

Memories that should be far away,
crash onto the shore with ease.

They say there is no time like today,
but thinking of them makes me wheeze.

Cautious as the wind,
mellow as the sand.

Whispers on my mind,
wishing they could land."
