Is Up Down?

I sat with my child, curious and inquisitive as she is,
asking me what was, what is that, and why does soda pop fizz.
She asked me why up is down, why people breath, whats the point of all of this?
I tried to pay attention, but she continued on with an endless list.
Why are you so tall, why do you go to work, what's the difference between a goat and a sheep?
I would have answered her questions,
but unfortunately I fell sound asleep.
