Seven A.M., the usual morning line-up

Start on the chores, and sweep 'til the floor's all clean

Polish and wax, do laundry and mop and shine up

Sweep again

And by then

It's, like, seven-fifteen

And so I'll read a book

Or maybe two or three

I'll add a few new paintings

To my gallery

I'll play guitar and knit and cook

And basic'ly

Just wonder, when will my life begin?

Then, after lunch, it's puzzles, and darts and baking...

Papier-maché, a bit of ballet, and chess...

Pottery and ventriloquy, candle-making...

Then I'll stretch

Maybe sketch

Take a climb

Sew a dress

And I'll re-read the books

If I have time to spare

I'll paint the wall some more

I'm sure there's room somewhere

And then I'll brush, and brush

And brush, and brush my hair

Stuck in the same place I've always been

And I'll keep won'dring

And won'dring

And won'dring

And won'dring

When will my life begin?

Tomorrow night...

The lights will appear

Just like they do on my birthday each year

What is it like

Out there where they glow?

Now that I'm older

Mother might just let me go...

Look the world

so close,and I'm halfway to it

Look at it all

so big,do I even dare?

Look at me

There at last

I just have do it

Should

No!

Here I go

just smell the grass! The dirt!

just like I dreamed they‘d be!

just feel that summer breeze

The way it's calling me

For like the first time ever, I'm completely free!

I could go running

And racing

And dancing

And chasing

And leaping

And bounding

Hair flying

Heart pounding

And splashingjust feel that summer breeze

The way it's calling me

For like the first time ever, I'm completely free!

I could go running

And racing

And dancing

And chasing

And leaping

And bounding

Hair flying

Heart pounding

And splashing

And reeling

And finally feeling

That's when my life begins!

And reeling

And finally feeling

That's when my life begins!
