Avocado Tree pt. 1

When I was little
I had an avocado tree
It grew and grew
Until it reached just below my knee
And I loved it, and it grew some more
And the sun shone and the rain poured
But it was potted in mere sand
That crumbled into dust
When I held it in my hand
The tree could grow no taller
And its roots could grow no deeper
In its little pot
