Shallow Waters

I'm adept at keeping secrets,
Almost to the point of genius.
Though I am tempted to speak up,
I am locked into my sequence

Which makes oceans look like puddles;
Trenches dwindle into potholes,
The lions roleplay as meerkats,
And crystal balls mimic bubbles.

Fallen prospects my achievements,
Many as I am facetious,
The treble conceals my troubles
Which bestow my regrets credence.

Joyful is my epithet, and
Even I can understand,
If the cover is so ornate,
The pages will be left unscanned.
