Answer:
I am there when you sit, but gone when you stand. What am I?
I am all around you but you cannot see me. I have no throat but you can hear me. Valued during summer but despised in the winter.
You throw away my outside, you cook my inside. Then you eat my outside and you throw away my inside. What am I?
I am a mother from a family of eight. Spins around all day despite my weight. Had a ninth sibling before founding out it's fake.
I have memories but none of my own whatever's on my inside is what is shown. If I'm ever different it's because you changed me I feel like a decoration here for you to arrange me.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
