Where Does The Water Go?

Boy (speaking): Mom, where does all the water go?

Mom (singing):
The water in the bath tub dear
It burbles down the drain
It takes a very long, long trip
And it ends up back as rain

I see that you remember these (?)
Now listen this is true
The water travels through a pipe
Not seen by me or you

It travels down the house and street
To rivers far away
To join the mighty ocean
Where it doesn't always stay
