Answer:
I am black and white. I have strings I have keys. I make sound without my lips. I make dough with no flour
I have fangs and enjoy piecing holes with a single bite.
Send poorly behaved children to me and let them sit here.
Every night I'm told what to do and each morning I do what I'm told. But I still don't escape your scold
I fly yet I have no wings. I cry yet I have no eyes. Darkness follows me. Lower light I never see.
When I'm born I fly. When I'm alive I lay. When I'm dead I run.
