Answer:
What bone has a sense of humor?
I hold two meanings. With one I may be broken with the other I hold on.
People walk in and out of me. They push me and I follow. When they walk out on me I close up and I stay waiting for the next person to walk into my life when I have a more open mind
The dirtier I get, the whiter I am. What am I?
The more you work the more I'll eat.You keep me full I'll keep you neat.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
