rub me and a genie might appear
You are my brother, but I am not your brother. Who am I?
My voice is tender my waist is slender and I'm often invited to play. Yet wherever I go I must take my bow or else I have nothing to say.
I come in different colors and shapes. Some parts of me are curvy, some are straight. I look like I can belong anywhere but there is only one right place for me. What am I?
You can catch me but cannot throw me.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
