Secrets Playing Hide-and-Seek

As I speak they just plop out,
Those little children running through the trees.
Playing hide-and-seek though they will never be found,
Laughter roams along the leaves.

Those little children trying to spill the beans,
But I shush them just in time to hide the spell.
And when those little children go to sleep,
I lock them safe inside a shell.

About the poem:The poem is about secrets.I compared the secrets to little children.I like to spend time in the woods and strangely i tell my secrets to the trees or to the plants(which is weird i know).The secrets are like little kids laughing and playing hide and seek but secrets are things that no one can know and so thats why i said that the children can "never be found".Kids always love to scream out everything they hear but the shell that i said they "get locked into" is a diary or a book.
