Reading Comprehension - Unseen Poem-5

Pockets

I think of all the things I have
I like my pockets best.
Pockets hold just everything
And they give your hands a rest.
I never know just what I'll find
What special things I'll see
To put inside my pockets ~~
These are treasures just for me.
When Mommy's doing laundry though
She says sometimes it's scary
Finding rocks and frogs and beetles
And my spiders that are hairy
