Mightier than the Sword! (I.P.)

What fun you could have being small,
if you were just two inches tall;
maybe ride on a snail’s back to school –
make a puddle your own private pool.

Not quite as minute as a flea –
yet invisible, almost, you’d be;
run amok in your sister’s long plaits
then watch as she scratched and she scratched.

If your form teacher kept you behind,
and insisted you had to do lines – say
to pick up a pen would take metal and might,
and his lines take you ten years to write!
