Don´t treat me like that!

I’m your doll.
You can play with me.
I like all your games.
You can do what you want with me.
I’ll always laugh,
Never cry, never hurt.
It’s easy!
You don’t need to care about me.
I’ll never get on your nerves.
I’m quiet if you don’t want me.
I don’t argue.
I’ll never leave you…

Why can’t YOU be MY doll?????
