WHAT AM I?

people move me in different ways.
sometimes they move me slow,
sometimes they move me fast.
how they'll move me next - i never know!

people feel content when they move me.
people move me while watching tv,
people move me while listening to music.
they find any excuse just to move me.

i'm not any burden to keep.
sometimes i grind or creak,
if you don't take care of me then -
i'll start to squeak!

almost every home has one.
i make kids smile,
i make adults relax.
people move me nonstop or awhile.

i don't know what else i can say about me.
i need to have my own special place,
i'll always be there for whenever you want me.
if people move me just right - i have grace.

i'm a rocking chair.
