Answer:
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.
My teeth are sharp my back is straight to cut things up it is my fate.
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched especially with a lot of force. I like to be in buildings.
Squeeze me and I cry tears as red as my flesh but my heart is made of stone.
I can be simple or I can be complex. I can be found in this riddle or in everyday life. I can be shapes or even colors.
As round as an apple. As deep as a cup. All the king's horses can't pull it up.
